Hi Everyone

I've been trying to import a mesh generated in a third-party package and run it in the incompressible solver. First, I tried a smaller mesh with a size of 10MB and 32 cores on an HPC with 3GB ram specified for each core. 
It worked and I proceeded to the main larger mesh with a size of 75MB and 128 cores. However, I found it can be quite challenging to establish a simulation as I often get MPI-related errors at the very beginning.
I was wondering if this is the standard way of handling large mesh files in parallel using mpirun:
mpirun -np 128 IncNavierStokesSolver condition.xml grid.xml

I am new to nektar++ so my question might seem trivial.

Kind regards
