René Flori General RFEM RSTAB

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

Answer

With RF-MAT NL we offer the use of different nonlinear material models. If you combine rods, surfaces and / or volumes in RFEM, the assignment of the nonlinear material models must be done individually for bars (1D) and surfaces and volumes (2D / 3D).

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