Solver stucks at initial time step

Please login with a confirmed email address before reporting spam

Dear all,

I'm trying to use an external model for material behavior of ferromagnetics. When I call the model via a .dll-file, the solver gets stucked at the initial time step. When I use COMSOL as Remote-Debugger within Visual Studio 2017, I can see that the solver doesn't leave the initial time step. The only output I get from the solver is "Matrices are assembled". Has anyone else experienced that kind of problem? I'd be grateful for any kind of support. Thanks in advance.
