4 | Chapter 1 Get Started With Stress AnalysisUsing Stress Analysis T ools
Autodesk Inventor Simulation Stress Analysis provides tools for determining
structural design performance directly on your Autodesk Inventor Simulation
model. Autodesk Inventor Simulation Stress Analysis includes tools to place
loads and constraints on a part and calculate the resulting stress, deformation,
safety factor, and resonant frequency modes.
Enter the stress analysis environment in Autodesk Inventor Simulation with
an active part.
With the stress analysis tools, you can:
■ Perform a stress or frequency analysis of a part.
Using Stress Analysis T ools | 5■ Apply a force, pressure, bearing, moment, or body load to vertices, faces,
or edges of the part, or apply a motion load directly to a part.
■ Apply fixed or non-zero displacement constraints to the model.
■ Evaluate the impact of multiple parametric design changes.
■ View the analysis results in terms of equivalent stress, minimum and
maximum principal stresses, deformation, safety factor, or resonant
frequency modes.
■ Add or suppress features such as gussets, fillets or ribs, re-evaluate the
design, and update the solution.
■ Animate part through various stages of deformation, stress, safety factor,
and frequencies.
■ Generate a complete and automatic engineering design report that can be
saved in HTML format.
Understanding the Value of Stress Analysis
Performing an analysis of a mechanical part in the design phase can help you
bring a better product to market in less time. Autodesk Inventor Simulation
Stress Analysis helps you:
■ Determine if the part is strong enough to withstand expected loads or
vibrations without breaking or deforming inappropriately.
■ Gain valuable insight at an early stage when the cost of redesign is small.
■ Determine if the part can be redesigned in a more cost-effective manner
and still perform satisfactorily under expected use.
Stress analysis, for this discussion, is a tool to understand how a design will
perform under certain conditions. It might take a highly trained specialist a
great deal of time performing what is often called a detailed analysis to obtain
an exact answer with regard to reality. What is often as useful to help predict
and improve a design is the trending and behavioral information obtained
from a basic or fundamental analysis. Performing this basic analysis early in
the design phase can substantially improve the overall engineering process.
Here is an example of stress analysis use: When designing bracketry or single
piece weldments, the deformation of your part may greatly affect the alignment
of critical components causing forces that induce accelerated wear. When
6 | Chapter 1 Get Started With Stress Analysisevaluating vibration effects, geometry plays a critical role in the resonant
frequency of a part. Avoiding or, in some cases, targeting critical resonant
frequencies literally is the difference between part failure and expected part
performance.
For any analysis, detailed or fundamental, it is vital to keep in mind the nature
of approximations, study the results, and test the final design. Proper use of
stress analysis greatly reduces the number of physical tests required. You can
experiment on a wider variety of design options and improve the end product.

Understanding How Stress Analysis Works
Stress analysis is done using a mathematical representation of a physical system
composed of:
■ A part (model).
■ Material properties.
■ Applicable boundary conditions and loads, referred to as preprocessing.
■ The solution of that mathematical representation (solving).
To find a solution, the part is divided into smaller elements. The solver
adds up the individual behaviors of each element to predict the behavior
of the entire physical system.
■ The study of results of that solution, referred to as post-processing.
Analysis Assumptions
The stress analysis provided by Autodesk Inventor Simulation is appropriate
only for linear material properties where the stress is directly proportional to
the strain in the material (meaning no permanent yielding of the material).
Linear behavior results when the slope of the material stress-strain curve in
the elastic region (measured as the Modulus of Elasticity) is constant.
Understanding How Stress Analysis Works | 7The total deformation is assumed to be small in comparison to the part
thickness. For example, if studying the deflection of a beam, the calculated
displacement must be less than the minimum cross-section of the beam.
The results are temperature-independent. The temperature is assumed not to
affect the material properties.
The CAD representation of the physical model is broken down into small
pieces (think of a 3D puzzle). This process is called meshing. The higher the
quality of the mesh (collection of elements), the better the mathematical
representation of the physical model. By combining the behaviors of each
element using simultaneous equations, you can predict the behavior of shapes
that would otherwise not be understood using basic closed form calculations
found in typical engineering handbooks.
The following is a block (element) with well-defined mechanical and modal
behaviors.
In this example of a simple part, the structural behavior would be difficult to
predict solving equations by hand.
8 | Chapter 1 Get Started With Stress AnalysisHere, the same part is broken into small blocks (meshed into elements), each
with well-defined behaviors capable of being summed (solved) and easily
interpreted (post-processed). For sheet metal, a special element type is used.
It is assumed that the model is thin in one direction relative to the size of the
other dimensions. The model has identical topologies on the top and bottom
and has only one topology through the thickness of the model.
Interpreting Results of Stress Analysis
The output of a mathematical solver is generally a substantial quantity of raw
data. This quantity of raw data would normally be difficult and tedious to
interpret without the data sorting and graphical representation traditionally
referred to as post-processing. Post-processing is used to create graphical
displays that show the distribution of stresses, deformations, and other aspects
of the model. Interpretation of these post-processed results is the key to
identifying:
■ Areas of potential concern as in weak areas in a model.
■ Areas of material waste as in areas of the model bearing little or no load.
■ Valuable information about other model performance characteristics, such
as vibration, that otherwise would not be known until a physical model
is built and tested (prototyped).
The results interpretation phase is where the most critical thinking must take
place. You compare the results (such as the numbers versus color contours,
movements) with what is expected. You determine if the results make sense,
and explain the results based on engineering principles. If the results are other
Interpreting Results of Stress Analysis | 9than expected, evaluate the analysis conditions and determine what is causing
the discrepancy.
Equivalent Stress
Three-dimensional stresses and strains build up in many directions. A common
way to express these multidirectional stresses is to summarize them into an
Equivalent stress, also known as the von-Mises stress. A three-dimensional
solid has six stress components. If material properties are found experimentally
by an uniaxial stress test, then the real stress system is related by combining
the six stress components to a single equivalent stress.
Maximum and Minimum Principal Stresses
According to elasticity theory, an infinitesimal volume of material at an
arbitrary point on or inside the solid body can be rotated such that only normal
stresses remain and all shear stresses are zero. When the normal vector of a
surface and the stress vector acting on that surface are collinear, the direction
of the normal vector is called principal stress direction. The magnitude of the
stress vector on the surface is called the principal stress value.
Deformation
Deformation is the amount of stretching that an object undergoes due to the
loading. Use the deformation results to determine where and how much a
part will bend, and how much force is required to make it bend a particular
distance.
Safety Factor
All objects have a stress limit depending on the material used, which is referred
to as material yield. If steel has a yield limit of 40,000 psi, any stresses above
this limit result in some form of permanent deformation. If a design is not
supposed to deform permanently by going beyond yield (most cases), then
the maximum allowable stress in this case is 40,000 psi.
10 | Chapter 1 Get Started With Stress AnalysisA factor of safety can be calculated as the ratio of the maximum allowable
stress to the equivalent stress (von-Mises) and must be over 1 for the design
to be acceptable. (Less than 1 means there is some permanent deformation.)
Factor of safety results immediately points out areas of potential yield, where
equivalent stress results always show red in the highest area of stress, regardless
of how high or low the value. Since a factor of safety of 1 means the material
is essentially at yield, most designers strive for a safety factor of between 2 to
4 based on the highest expected load scenario. Unless the maximum expected
load is frequently repeated, the fact that some areas of the design go into yield
does not always mean the part will fail. Repeated high load may result in a
fatigue failure, which is not simulated by Autodesk Inventor Simulation Stress
Analysis. Always, use engineering principles to evaluate the situation.
Frequency Modes
Use vibration analysis to test a model for:
■ Its natural resonant frequencies (for example, a rattling muffler during idle
conditions, or other failures)
■ Random vibrations
■ Shock
■ Impact
Each of these incidences may act on the natural frequency of the model,
which, in turn, may cause resonance and subsequent failure. The mode shape
is the displacement shape that the model adopts when it is excited at a
resonant frequency.
Frequency Modes | 1112Analyze Models
Once your model is defined, define the loads and constraints for the condition you want to
test, and then perform an analysis of the model. Use the stress analysis environment to prepare
your model for analysis, and then run the analysis.
This chapter explains how to define loads, constraints, and parameters, and run your analysis.
Working in the Stress Analysis Environment
Use the stress analysis environment to analyze your part design and evaluate
different options quickly. You can analyze a part model under different
conditions using various materials, loads, and constraints (or boundary
conditions), and then view the results. You have a choice of performing a stress
analysis, or a resonant frequency analysis with associated mode shapes. After
viewing and evaluating the results, you can change your model and rerun the
analysis to see what effect your changes produced.
You can enter the stress analysis environment from the part and sheet metal
environments.
Enter the stress analysis environment
1 Start with the part or sheet metal environment active.
2 Click Applications ➤ Stress Analysis.
The Stress Analysis panel bar displays.
2
13Loads and constraints are listed under Loads & Constraints in the browser. If
you right-click a load or constraint in the browser, you can:
■ Edit the item. The dialog box for that item opens so that you can make
changes.
■ Delete the item.
To rename an item in the browser, click it, enter a new name, and then press
ENTER.
Running Stress Analysis
Once you build or load a part, you can run an analysis to evaluate it for its
intended use. You can perform either a stress analysis or a resonant frequency
analysis of your part under defined conditions. Use the same workflow steps
in either analysis.
The following are the basic steps to perform a stress or resonant frequency
analysis on a part design.
14 | Chapter 2 Analyze ModelsWorkflow: Perform a typical analysis
1 Enter the stress analysis environment.
2 Verify that the material used for the part is suitable, or select one.
3 On the Stress Analysis panel bar, select the type of load to apply. The
choices are Force, Pressure, Bearing Load, Moment, Body Load, Motion
load (for a part exported from Dynamic Simulation), or Fixed Constraint.
4 On the model, select the faces, edges, or vertices where you want to apply
the load.
5 Enter the load parameters (for example, on the Force dialog box, enter
the magnitude and direction). Numerical parameters can be entered as
numbers or equations that contain user-defined parameters.
6 Repeat steps 3 through 5 for each load on the part.
7 Apply constraints to the model.
8 Change stress analysis environment settings as needed.
9 Modify or add parameters as needed.
10 Start the analysis.
11 View the results.
12 Change the model and reanalyze it until you simulate the appropriate
behavior.
Verifying Material
The first step is to verify that your model material is appropriate for stress
analysis. When you select Stress Analysis, Autodesk
®
Inventor

checks the
material defined for your part. If the material is suitable, it is listed in the
Stress Analysis browser. If it is not suitable, a dialog box is displayed so that
you can select a new material.
Verifying Material | 15You can cancel this dialog box and continue setting up your stress analysis.
However, when you attempt a stress analysis update, this dialog box is
displayed so you can select a valid material before running the analysis.
If the yield strength or density are zero, you cannot perform an analysis.
Once you select a suitable material, click OK.
Applying Loads
The first step in preparing your model for analysis is applying one or more
loads to the model.
Workflow: Apply loads for analysis
1 Select the type of load you want to apply.
2 Select the geometry of the model where the load is applied.
3 Enter the required information for that load.
You can apply as many loads as you need. As you apply them, the loads are
listed in the browser under Loads & Constraints. Once you define a load, you
can edit it by right-clicking it, and then selecting Edit from the menu.
Select and apply a load
1 In the stress analysis environment, Stress Analysis panel bar, click Force.
16 | Chapter 2 Analyze ModelsAfter you select Force, you define the force on the Force dialog box.
2 Click faces, edges, or vertices on the part to select them. Use CTRL-click
to remove a feature from the selection set.
Once you select an initial feature, your selection is limited to features of
the same type (only faces, only edges, only vertices). The location arrow
turns white.
3 Click the direction arrow to set the direction of the force. You can set the
direction normal to a face or work plane, or along an edge or work axis.
Applying Loads | 17When the force location is a single face, the direction is automatically
set to the normal of the face, with the force pointing to the outside of
the part.
4 To reverse the direction of the force, click the Flip Direction button.
5 Enter the magnitude of the force.
6 To specify the force components, click the More button to expand the
dialog box, and then select the check box for Use Components.
7 Enter either a numerical force value or an equation using defined
parameters. The default value is 100 in the unit system defined for the
part.
8 Click OK.
An arrow is displayed on the model indicating the direction and location
of the force.
You follow a similar procedure for each of the different load types.
18 | Chapter 2 Analyze ModelsThis table summarizes information about each load type:
Load-Specific Information Load
Apply a force to a set of faces, edges, or vertices. When the
force location is a face, the direction is automatically set to
Force
the normal of the face, with the force pointing to the inside
of the part. Define the direction planar faces, straight edges,
and axes.
Pressure is uniform and acts normal to the surface at all loca-
tions on the surface. Apply pressure only to faces.
Pressure
Apply a bearing load only to cylindrical faces. By default, the
applied load is along the axis of the cylinder and the direction
of the load is radial.
Bearing

Rotational Velocity. You can only apply one body load per
analysis.
Applying Constraints
After you define your loads, specify the constraints on the geometry of the
part. You can apply as many constraints as you need. The defined constraints
are listed in the browser under Loads & Constraints. After you define a
constraint, you can edit it by right-clicking it, and then selecting Edit from
the menu.
Select and apply a constraint
1 On the Stress Analysis panel bar, click Fixed Constraint, Pin Constraint,
or Frictionless Constraint.
2 In the graphics window, select a set of faces, edges, or vertices to constrain.
The location arrow turns white.
Applying Constraints | 193 Click the More button to specify a fixed displacement for the constraint,
if needed. Check Use Components, and then check the box next to the
global axis label (X, Y, or Z) along which the displacement occurs.
You can use parameters and negative values. Use Components to specify
a non-zero displacement that can be used as a load.
4 Click OK.
Setting Parameters
When you define loads and constraints for a part, the values you enter
(magnitudes, vector components, and so on) are stored as parameters in
Inventor. It automatically generates the parameter names. For example, load
parameters are labeled dn, where d0 is the first load created, d1 the second
load, and so on.
Load magnitude and constraint displacement values can be entered as
equations when you are defining them. Or, after defining the loads and
constraints, select Parameters from the stress analysis panel bar. On the
Parameters dialog box, enter equations for any of the load or constraint
parameters.
20 | Chapter 2 Analyze ModelsYou can define and edit parameters at any time, either during part modeling,
analysis setup, or post-processing. If you change the parameters associated
with a load or constraint after a solution is obtained, the Update command
is enabled so you can run a new solution.
You cannot delete the system-generated parameters, although they are deleted
automatically if their associated loads or constraints are deleted. You also
cannot delete parameters that are currently used by a system-generated
parameter.
Feature Suppression Tracking
When conducting analysis studies, you may need to tailor portions of a model
to allow for a more efficient analysis. Generally, this technique involves
removing geometrically small features which only complicated the mesh,
without significant effects to the final result.
Setting Solution Options
Before starting your solution, set the analysis type and mesh relevance for the
analysis, and then specify whether to create new analysis file. Select Stress
Analysis Settings from the stress analysis panel bar to open the dialog box.
When you finish setting the options, click OK to commit them.
Feature Suppression Tracking | 21Setting Analysis T ype
Before starting your solution, on the Settings dialog box, Analysis Type, select
Stress Analysis, Modal Analysis (to perform resonant frequency analysis) or
Both (to run a stress analysis and a prestressed modal analysis of your part).
Setting Mesh Control
There are two meshing model types: standard solid model and optimized thin
model. For a part, the default is standard solid model. It can be meshed in all
X, Y, and Z directions. The default meshing model for sheet metal is optimized
thin model. It is assumed that the model is thin in one direction relative to
the size of the other dimensions, has identical topologies on the top and
bottom, and has only one topology through the thickness of the model. On
the Settings dialog box, move the Mesh Relevance slider to set the size of your
mesh. The default value of zero is an average mesh. Setting the slider to 100
causes a fine mesh to be used. It gives you a highly accurate result, but causes
the solution to take a longer time. Setting the slider to -100 gives you a coarse
mesh, which solves quickly, but may contain significant inaccuracies. The
Mesh Relevance and Result Convergence only work for the standard solid

Obtaining Solutions
After you complete all the required steps, the Stress Analysis Update command
on the Standard toolbar is active. Select it to start the solution.
The Solutions Status dialog box is displayed while the solution is in progress.
During the solution, Autodesk Inventor Simulation is unavailable. Once the
solution finishes, the results are displayed graphically.
For information about reviewing the results of your solution, see View Results
on page 25.
Running Modal Analysis
In addition to the stress analysis, you can perform a resonant frequency (modal)
analysis to find the frequencies at which your part vibrates, and the mode
shapes at those frequencies. Like stress analysis, modal analysis is available in
the stress analysis environment.
You can do a resonant frequency analysis independent of a stress analysis.
You can do a frequency analysis on a prestressed structure, in which case you
can define loads on the part before the analysis. You can also find the resonant
frequencies of an unconstrained part.
Your initial steps must be the same as for stress analysis. Refer to the
instructions in Running Stress Analysis on page 14 to set up your loads,
constraints, parameters, and solution options.
Obtaining Solutions | 23Workflow: Run a modal analysis
1 Enter the stress analysis environment.
2 Verify that the material used for the part is suitable, or select one.
3 Apply any loads (optional).
4 Apply the necessary constraints (optional).
5 Before starting the solution, on the Settings dialog box, Analysis Type
section, select Modal Analysis.
Selecting Both runs a stress analysis and a modal analysis of your part.
Selecting a modal analysis with a load applied produces a prestressed
modal solution.
6 Click OK.
The results for the first six frequency modes are inserted under the Modes
folder in the browser. For an unconstrained part, the first six frequencies
are essentially zero.
7 To change the number of frequencies displayed or limit the range of
frequency results returned, right click the Modes folder, and then select
Options.
The Frequency Options dialog box is displayed. Enter the maximum
number of modes to find, or the range of frequencies to which you want
to limit the results set.
After you complete all the required steps, the Stress Analysis Update
command on the standard toolbar is active.
8 Select Stress Analysis Update to start the solution.
The Solutions Status dialog box is displayed while the solution is in
progress. Once the solution finishes, the results are available for viewing.
24 | Chapter 2 Analyze ModelsView Results
After analyzing your model under the stress analysis conditions that you defined, you can
visually observe the results of the solution.
This chapter describes the how to interpret the visual results of your stress analyses.
Using Results Visualization
Use results visualization to see how your part responds to the loads and
constraints you apply to it. You can visualize the magnitude of the stresses that
occur throughout the part, the deformation of the part, and the stress safety
factor. For modal analysis, you can visualize the resonant frequency modes.
Enter results visualization
1 Start in the stress analysis environment. Open a part or sheet metal part
that was analyzed previously, or complete the required steps in your current
analysis.
2 On the standard toolbar, click the Stress Analysis Update tool.
The color bar displays in the graphics window.
Post-processing commands are enabled on the standard toolbar, and the display
mode shifts to stepped contours.

25To view the different results sets, double-click them in the browser. While
viewing the results, you can:
■ Change the color bar to emphasize the stress levels that are of concern.
■ Compare the results to the undeformed geometry.
■ View the mesh used for the solution.
Use the normal view controls to manipulate the model for a 3-dimensional
view of the results.
To change any model parameters, return to part modeling, and then return
to stress analysis and update the solution.
Editing the Color Bar
The color bar shows you how the contour colors correspond to the stress
values or displacements calculated in the solution. You can edit the color bar
to set up the color contours so that the stress/displacement is displayed in a
way that is meaningful to you.
26 | Chapter 3 View ResultsEdit the color bar
1 Click Color Bar on the Stress Analysis panel bar.
By default, the maximum and minimum values shown on the color bar
are the maximum and minimum result values from the solution. You
can edit the extreme maximum and minimum values, and the values at
the edges of the bands.
2 To edit the maximum and minimum critical threshold values, click the
Automatic check box to clear the selection, and then edit the values in
the text box. Click Apply to complete the change.
To restore the default maximum and minimum critical threshold values,
select Automatic, and then click Apply.
The levels are initially divided into seven equivalent sections, with default
colors assigned to each section. You can select the number of contour
colors in the range of 1 to 12.
3 To increase or decrease the number of colors, click the Increase
Colors and Decrease Colors buttons. You can also enter the number of
colors you want in the text box.

click Apply.
The color bar preferences such as color, position, and size are applied to
all of the result types.
The Maximum and Minimum threshold values, number of colors and
Invert colors preferences are applied only to the selected result type.
Editing the Color Bar | 27Reading Stress Analysis Results
When the analysis is complete, you see the results of your solution. If you did
a stress analysis or specified that both types of analyses to do, you initially see
the equivalent stress results set displayed. If your initial analysis is a resonant
frequency analysis (without a stress analysis), you see the results set for the
first mode. To view a different results set, double-click that results set in the
browser pane. The currently viewed results set has a check mark displayed
next to it in the browser. You always see the undeformed wireframe of the
part when you are viewing results.
Interpreting Results Contours
The contour colors displayed in the results correspond to the value ranges
shown in the legend. In most cases, results displayed in red are of most interest,
either because of their representation of high stress or high deformation, or
a low factor of safety. Each results set gives you different information about
the effect of the load on your part.
Equivalent Stress
Equivalent stress results use color contours to show you the stresses calculated
during the solution for your model. The deformed model is displayed. The
color contours correspond to the values defined by the color bar.
Maximum Principal Stress
The maximum principal stress gives you the value of stress that is normal to
the plane in which the shear stress is zero. The maximum principal stress helps
you understand the maximum tensile stress induced in the part due to the
loading conditions.
28 | Chapter 3 View ResultsMinimum Principal Stress
The minimum principal stress acts normal to the plane in which shear stress
is zero. It helps you understand the maximum compressive stress induced in
the part due to the loading conditions.
Deformation
The deformation results show you the deformed shape of your model after
the solution. The color contours show you the magnitude of deformation
from the original shape. The color contours correspond to the values defined
by the color bar.
Safety Factor
Safety factor shows you the areas of the model that are likely to fail under
load. The color contours correspond to the values defined by the color bar.
Frequency Modes
You can view the mode plots for the number of resonant frequencies that you
specified in the solution. The modal results appear under the Modes folder in
the browser. When you double-click a frequency mode, the mode shape is
displayed. The color contours show you the magnitude of deformation from
the original shape. The frequency of the mode shows in the legend. It is also
available as a parameter.
Animate Results
Use the Animate Results tool to visualize the part through various stages of
deformation. You can also animate stress, safety factor, and deformation under
frequencies.

38 | Chapter 5 Generate ReportsManage Stress Analysis
Files
Running a stress analysis in Autodesk
®
Inventor

Simulation creates a separate file that
contains the stress analysis information. In addition, the part file is modified to indicate the
presence of a stress file and the name of the file.
This chapter explains how the files are interdependent, and what to do if the files become
separated.
Creating and Using Analysis Files
You can run a stress analysis by creating a part in Autodesk Inventor Simulation,
and then setting up your stress analysis conditions. You can also load a part
that you previously created, on which you have not yet run a stress analysis,
and set up your analysis conditions. Once you set up a stress analysis for a part,
when you save the part you also save the stress analysis information for that
part.
Start a new analysis
1 Load an existing part or create a part in the part or sheet metal
environments.
2 Enter the stress analysis environment by clicking Applications ➤ Stress
Analysis.
3 Set up your analysis conditions.
After you set up any stress analysis information, saving your part also saves the
associated stress analysis information in the part file. Stress analysis input and
results information, including loads, constraints, and all results, is also saved
6
39in a separate file. The stress analysis file has the same name as your part file,
but uses the extension .ipa. By default, the .ipa file is stored in the same folder
as the .ipt file.
The _structure.rst (for stress analysis) and the _modal.rst (for modal analysis)
files, used to export to ANSYS, are generated after you save. If you select both,
the _strucure.esave and _structure.db files, used to export to ANSYS, are also
generated and stored in a subfolder like the .ipt file.
Understanding File Relationships
Activating the stress analysis environment, and then saving the .ipt file does
not create the analysis files. Add at least one stress analysis update before
Autodesk Inventor Simulation creates the .ipa file.
The analysis files contain information that indicates which .ipt file is associated
with the .ipa file. Multiple .ipt files cannot reference the same .ipa file, and
multiple .ipa files cannot reference the same .ipt file.
The Save Copy As command does not generate a new .ipa file. This means
that the new .ipt file references the same .ipa file as the old .ipt file.
On the Stress Analysis Setting dialog box, use the Create OLE Link to Result
Files option to keep the relationship between the analysis files except for the
.ipa and .ipt files. If the option is checked, the files are necessary to open the
.ipt file.
For more information about the Save Copy As command, see Copying
Geometry Files on page 41 in this chapter.
NOTE An existing .ipa file is not loaded until you activate the stress analysis
environment.
Repairing Disassociated Files
Under certain circumstances, edit the part file without the presence of the .ipa
file. For example, you sent the .ipt file but not the .ipa file to a consultant.
You can edit the part file through the Skip option on the Resolve Link dialog
box.
If you edit the part while the .ipa file is missing, and then try to reassociate
the part with its analysis file, Inventor makes an attempt to update the stress
40 | Chapter 6 Manage Stress Analysis Filesconditions. There is a possibility that errors can occur when you try to
reassociate the files.
Copying Geometry Files
You can create a copy of an .ipt file using the Save Copy As command or your
operating system file copy command. The copy of the .ipt file still references
the original .ipa file.
Resolving File Link Failures
In some cases, the .ipa file might fail to resolve when you try to perform an
analysis of the part. For example, you rename or move the .ipa file, or a vendor
receives a copy of an .ipt file without the associated .ipa file. The .ipa file fails
to resolve and you are prompted with the Resolve Link dialog box.
You can do two things, other than cancel the file open process:
■ Skip the file.
■ Select an existing .ipa file.
Skipping Missing IPA Files
If you select to edit a part even though the .ipa file is missing, you can enter
the stress analysis environment. Create an .ipa file by rerunning the stress
analysis update and saving. You can edit the part document itself. However,
you cannot perform any stress analysis work.
Selecting Existing IPA Files
If the .ipa file is missing, you can select an existing renamed or moved .ipa
file.
Copying Geometry Files | 41Creating New Analysis Files
To create an .ipa file, click the Stress Analysis Update button on the standard
toolbar and save it. Inventor attempts to create an .ipa file in the default
location using the default name.
If a file exists using this name and location, Inventor checks the .ipa file to
see if it points to the active .ipt file. If it does, the new .ipa file replaces the old
one.
When you create a file, the new .ipa file has boundary conditions that match
the conditions stored in the .ipt file.
Exporting Analysis Files
To run a more complex analysis on your part than Autodesk Inventor
Simulation Stress Analysis can handle, export your current analysis information
to a file that ANSYS WorkBench can import.
