Harmonic Analysis with Ansys APDL: Obtaining Strain and Stress Solutions

Click For Summary

Discussion Overview

The discussion revolves around obtaining strain and stress solutions from a harmonic analysis conducted using Ansys APDL. Participants are exploring the challenges faced in extracting these results after completing the analysis, as well as inquiries about design optimization features in different versions of Ansys APDL.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant, Tonino Sepe, reports having completed a harmonic analysis but only obtained DOF solutions, seeking guidance on how to extract strain and stress solutions.
  • Another participant suggests that finding the correct command in the documentation may resolve the issue, referencing ANSYS's documentation and a specific example.
  • Tonino Sepe indicates that they have already consulted the documentation and example but still cannot find the strain and stress information post-analysis.
  • A participant questions whether Tonino's problem is indeed resolved, implying uncertainty about the analysis outcome.
  • Tonino Sepe expresses confidence that the analysis is correct despite the missing strain and stress data.
  • A different participant discusses a transition from ANSYS APDL 12 to 15, noting the absence of a "design opt" feature in the newer version and seeking advice on applying design optimization.
  • Responses to the design optimization inquiry indicate a lack of familiarity with the specific feature, prompting a request for clarification on the geometry aspects to optimize for harmonic response.

Areas of Agreement / Disagreement

Participants do not reach a consensus regarding the extraction of strain and stress solutions, as Tonino Sepe believes the analysis is correct while others question the resolution of the problem. Additionally, there is no agreement on the design optimization feature's availability in different versions of Ansys APDL.

Contextual Notes

Participants express uncertainty about the specific commands needed to extract strain and stress solutions, and there are unresolved questions regarding the design optimization features in different versions of Ansys APDL.

Who May Find This Useful

This discussion may be useful for users of Ansys APDL who are conducting harmonic analyses and seeking to extract strain and stress results, as well as those interested in design optimization features across different software versions.

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)
