Dear STKO Team,

I am writing to request your assistance with a problem I'm encountering in my axial compression model.

I have successfully set up a model to output results for corner nodes. However, I'm experiencing difficulties when trying to record stress data for corner node elements. Despite trying various approaches, I cannot properly capture the stress in these elements.

I've attached my code and relevant details below for your reference. Could you please review this and advise on where the issue might be?

Thank you for your time and assistance.

Best regards,

Monace

Isn't it easier to extract stress/strain data using the Extract Chart Data feature in STKO? If you want to manually use a recorder, you have to deal with mesh partitioning

Dear STKO Team,

Thank you for your continued support. I appreciate the assistance you've provided thus far.

Regarding my current issue, I've been trying to record displacement and acceleration data through manual node recording, which has been successful. However, I'm encountering problems when attempting to record stress and strain values using elements with the ASDConcrete3D constitutive model.

Interestingly, the same recording code works perfectly when used with the PDMY02 constitutive model for liquefaction analysis, but fails to record the corresponding information when I switch to the ASDConcrete3D model.

I suspect there might be an issue with my recording code that's specific to the ASDConcrete3D implementation. Could you please help me review and modify my code to properly record stress and strain data for this constitutive model?

I would greatly appreciate your expertise in resolving this issue.

Thank you in advance for your assistance.

Best regards,

This is wrong This is fine In OpenSees the number after the material keyword is the 1-based index of the gauss point. (and your material doesn't have 26 gauss points)

Got it, Thank you!

You're welcome
