  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:

  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
