Error: RandomizedMaterialWrapper "invalid literal for int(): 'rebar'"

[amb_1]

Dear STKO Team,
I need help resolving an error when switching from ASD3D to RandomizedMaterialWrapper in an eccentric column model.

Issue:
Model works with ASD3D.
Fails with RandomizedMaterialWrapper, throwing:
invalid literal for int() with base 10: 'rebar' (new error).

Actions:
Checked material definitions, input files (attached), and documentation—no solution found.
Questions:
Are additional inputs required for RandomizedMaterialWrapper?
Could parameter parsing (e.g., string vs. integer) cause this?

Attachments:
Input files (working/error versions).
Error screenshot.
Thank you for your support.
Best regards,

Dear STKO Team,

I am writing to seek your technical support regarding an issue encountered during my recent testing. After troubleshooting, I identified that the problem likely stems from the Recorder function: the software operates normally when the Recorder is removed, but fails to generate output when the Recorder is enabled. This suggests a potential conflict or bug within the Recorder module. Could you kindly investigate this behavior?

Thank you for your prompt attention to this matter.

I cannot reproduce the error with my STKO version 4.0.0.
What version are you using?
