When using nonlinear material, I get an error message, what should I do?


With RF-MAT NL, we offer the use of various nonlinear material models. If members, surfaces, and/or solids are combined in RFEM, the nonlinear material models must be assigned individually for members (1D) and surfaces and solids (2D/3D).

Members as 1D elements can not be assigned a nonlinear material model (2D/3D).
