Hi Wenlong,


Thank you very much for your response. I'm kind of confused, why it seems like I don't have the option for selecting "hill yield criterion" as showen in the screenshot below:


Baustahl is german for structural steel.

Same issue if i choose Edelstahl NL (stainless steel non-linear) or Baustahl NL (structural steel non-linear).

Do I need to import some additional libaries? I can't quiet read your sources, but i guess it says "general_materials.xml"?
