Dear STKO Team,
Thank you for your prompt reply.
1- To use DamageTC3D instead of PSUMAT material, I tried to analyze the model displayed in the webinar of Shear Wall. The analysis is completed, but unfortunately no damage is displayed (d+ d- equal 0 for all steps). Could I ask you about this matter ...

Dear STKO Team,
The clause “PSUMAT - NOT DEFINED IN THIS VERSION, SOURCE CODE RESTRICTED” is appeared when openseesmp solver is used to analyze LayeredShell section with PlaneStressUserMaterial and PlateFromPlaneStress. Analysis successfully finished after too long time with repeating that clause ...

Dear STKO Team,
Could you please share the reference or paper you depend on to calculate the value of normal and tangential penalty in your last webinar for the interface between soil and foundation?
Kind regards,
Rania

Dear STKO Team,
It’s done. Thank you very much for your reply and efforts.

Dear STKO Team,
That’s great, thank you very much for your prompt reply and help.
Please, could I ask you some questions?
