Hi all,

I am simulating a model using microwaves heating in the Heat Transfer module using COMSOL 5.2. But I am getting the following error while simulating:

Fatal error during assembly or evaluation.
- Detail: Undefined value for Jacobian of field component

Can any body please let me know how to fix this error?

Thank you!
