Hello all.
I am trying to model a problem attached as a picture, it consists of a copper heat sink, and a GaAs block atop it. A voltage of 10V is applied as a Terminal to the GaAs while ground exists at the base of the heat sink. However, when modelling this problem I encounter an error, the relative error is greater than relative tolerance error.
Wondering if you have any suggestions how to fix this problem. I can upload my mph file if needed.
Thank you.

The error message may be due to not having enough Dirichlet constraints. You can look for more suggestions from others as I am very new to comsol.
