Hi
I just faced a strange problem with COMSOL, I have a time dependent model which runs perfectly fine from t=0 to t=1e-6[s]. In this model I divide the interval into 20 steps for getting results: range(0,1e-6/20,1e-6).
When I try to run this model from t=0 to t=2e-5[s] with 20 equal steps, the model stops somewhere around t=1e-10 "Nonlinear solver did not converge; Undefined value found; Undefined value found in stiffness matrix".
This doesn't make sense at all, Could somebody here help me with this please?
By the way; I set the "Steps taken by the solver" as "Free" in the "Study 1=>Solver 1=>Time-Dependent Solver 1=> Time Stepping" section.
Regards,
Peyman.
