Question:
When using nonlinear material, I get an error message; what should I do?
Answer:
RF‑MAT NL allows you to use various nonlinear material models. If you combine members, surfaces, and/or solids in RFEM, it is necessary to assign the nonlinear material models individually to members (1D) as well as to surfaces and solids (2D/3D).
The nonlinear material model (2D/3D) cannot be assigned to the members as 1D elements.
