I have a very simple question regarding a model that I am trying to create. It consists of two domains having boundary conditions at the interfaces (or boundaries in Comsol).

I have successfully meshed it. I tried solving it using a nonlinear solver as mine is a non-linear problem and with no success. As soon as the solver starts, there is an error no. 7248 that shows up as:


Exception:
com.femlab.jni.FlNativeException: Undefined value found Solvermodel

Could you please suggest me a solution as quickly as possible to get this working.

Thanks in advance.
