Hi Joerg,

You are welcome. I contacted one of the developers about this and he said "Doing the initial analysis using elastic material is not a good idea as it would not capture the relevant history variable values. Also, recommended practice is to use separate material properties for different layers, and not use B etc."

I hope this addresses your concern.

Thanks,

Pedram
