Drift-diffusion simulation for 3D produces higher currents than expected

Hi @AlexBur

Thank you for the investigation. As a result, I was able to identify a missing keyword from the:
devsim.get_equation_command

and put this into the Version 2.8.3 Release

While Intel MKL Pardiso is the default solver on x86_64 Windows and Linux, sometimes there are cases which fail to converge. UMFPACK is the alternative solver, and the default on Linux aarch64 and macOS. As the solvers are currently configured in devsim, UMFPACK succeeded in convergence while the other could not.

On my TODO list is to begin creating Knowledge Base topics in this forum, so that others may have an easier time debugging simulation issues.
