    As the error indicate, the system libraries required to run the simulation with Intel MPI is not found on your node(s) that are trying to run the simulation job. Specifically, the shared libraries. Please consult with your IT or cluster admin to check if there is a different version installed on your cluster and to use that. Might have to create a symlink for your Intel MPI version in your environment.

    Otherwise try to run the simulation using the bundled MPICH2. Running directly from the command prompt/terminal with the default install path for the latest release 2021 R1 ;

    $ /opt/lumerical/211/mpich2/nemesis/bin/mpiexec -n 8 /opt/lumerical/211/bin/fdtd-engine-mpich2nem -t 1 -logall -fullinfo cell2.fsp
