I would like to add another key to the materials. It is another stress needed to implement plastic material in FEM. What do I need to do for this?
- add it to the template file /src/Mod/Material/StandardMaterial/TEMPLATE.FCMat https://github.com/FreeCAD/FreeCAD/blob ... LATE.FCMat
- add the new key and the value to the materials
- what else ?!?
