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.
