-Since M3D simulation is kind of complex compared to 2D and 2.5D simulations, it is recommended to disable the ZOLTAN load balancer and choose the flat round-robin partitioning strategy for parallel thermal simulations. Users can achieve these by uncommenting lines 284 and 286 in ~/src/SPICESolver_transient.py and line 326 in ~/src/SPICESolver_steady.py.
