      How to run Lumerical file on HPC (Linux), please?

      I have problem with submitting my job script.

      Lumerical module installed on the HPC system is called:

      apps/lumerical-fdtd/2021-r2

      Please see attached screenshots...

      Thank you, Lito.
      What is the difference between:
      fdtd-engine-ompi-lcl
      and
      fdtd-solutions
      please?
      (We want distributed computing instead of parallel computing, multiple processors performing one just one job.)
      What is the command for running: fdtd-solutions, please?
      The command for running: fdtd-engine-ompi-lcl is:
      mpirun -np $SLURM_NTASKSfdtd-engine-ompi-lcltest.fsp

      "fdtd-solutions" is the CAD/GUI component of FDTD. This is run/executed from your Desktop/Graphical environment which requires a GUI/graphical connection on the Linux machine. Typically on clusters, you do not have GUI access/graphical connection. You run the simulation file from the command prompt using the solver/engine component of FDTD.
      cd /path_of_your_simulation_file/
      module load openmpi #load your OpenMPI
      mpirun /opt/lumerical/v221/bin/fdtd-engine-ompi-lcl -t 1 yoursimulationfile.fsp
