Harmonic Analysis with Ansys APDL: Obtaining Strain and Stress Solutions

Click For Summary
SUMMARY

The discussion centers on performing Harmonic Analysis using Ansys APDL 17.0, specifically focusing on obtaining strain and stress solutions after the analysis. User Tonino Sepe reports that while he can access the Degrees of Freedom (DOF) solution, he is unable to retrieve strain and stress data. Other participants suggest consulting ANSYS documentation and examples, but Tonino confirms he has already done so without success. Additionally, there is a mention of the absence of the "design opt" feature in Ansys APDL 15, which was available in version 12, raising questions about design optimization capabilities in the newer version.

PREREQUISITES
  • Understanding of Harmonic Analysis in Ansys APDL
  • Familiarity with obtaining and interpreting DOF solutions
  • Knowledge of strain and stress analysis in finite element modeling
  • Experience with version differences in Ansys APDL (e.g., 12 vs. 15 vs. 17.0)
NEXT STEPS
  • Review ANSYS documentation on extracting strain and stress solutions post-analysis
  • Explore the differences in design optimization features between Ansys APDL versions
  • Learn about comparing Frequency Response Function (FRF) results from analysis and experimental tests
  • Investigate alternative commands or methods in Ansys APDL for obtaining strain and stress data
USEFUL FOR

Engineers and analysts working with finite element analysis in Ansys APDL, particularly those focused on harmonic response and optimization techniques.

Hi everyone,
I have done the Harmonic Analysis of my model with Ansys APDL 17.0 (ACADEMIC version), and I have obtained only the DOF solution of my nodes but i need the Strain and Stress solution . How can I get it?
Thanks.
Tonino Sepe.

I have already checked the Ansys documentation and the example, i know how to plot the strain of a node vs frequency range but the problem is that these informations after the analysis there aren't. I don't know why.
 
Are you sure your problem is coming to a solution?
 
I think yes, the analysis is correct.
 
HI,
i was using ANSYS APDL 12 and there was a "design opt" in the main menu tree to the left. it s for design optimization. however now i built my model in ansys apdl 15 but there s no longer "design opt" in it. any ideas how to apply design optimization in apdl 15??
thanks
 
Sorry, I haven't used the feature you're trying to. What specific features of your geometry are you trying to optimize for harmonic response?

I m trying to update my FE model with the harmonic test results (i.e. compare FRF results from analysis and test)
