Prestress script to increment applied prestress

Dear STKO

I have been trying to follow Dr. Massimo's YouTube "New Element- Embedding Rebars into Solid Domains", at about the 44 min mark. I have also searched this forum for more help.

I am creating a prestressed beam, following exactly Dr. Massimo's procedure. The issue is I keep getting an error "WARNING: InitStressMaterial - could not find initStrain to within tol for material: 5 wanted sigInit: 0 using tStress: 0"

Is there an example file from that video that I can download, to see where my issue is?

Also, does this scripting procedure work if I am using OpenSeesMp?

Thank you so much.

"WARNING: InitStressMaterial - could not find initStrain to within tol for material: 5 wanted sigInit: 0 using tStress: 0
this is just a warning due to internal very strict tolerances they use in InitStressMaterial.
For more info you should share your model
