I have a problem regarding the definition of multiple boundary conditions in AceFEM. I am dealing with coupled problem simulations (displacement and magnetic potential) and therefore I have to apply different boundary conditions simultaneously. For some analyses, the potential is varied by a load factor. This works well. Now I have the problem, that I want to apply the load factor to the potential but I also want to apply a constant (non-zero) displacement simultaneously.

Is there a way that the load factor only affects the potential and the displacement remains constant?

Thank you in advances,

Max

You should prescribe displacements boundary conditions with the command SMTAddInitialBoundary[..., "EssentialBoundary"->True] Prescribed in this way BC will not be scaled with the load factor.
