      Can we configure resources in Lumerical Charge and other multi-physics solvers the same way as in Lumerical FDTD?

      No, the resource configuration in Lumerical's multi-physics simulation tools, including Charge, differs from the FDTD solver. However, you can adjust the threading options within the solver itself.

      How to Configure Threading Options in Lumerical Charge:

      1. Edit Simulation Solver Properties:

        • Right-click on the solver region in your simulation file and select "Edit."
        • Navigate to the "Advanced" tab to access multithreading options.

      2. Set Thread Count :

        • In the multithreading drop-down menu, choose "Set Thread Count."
        • Specify the desired number of threads. This number should be less than or equal to the total number of cores on your computer for optimal performance.

      Command Line Execution:


        • Alternatively, use the command line to run the simulation with the "-t #" argument, where "#" represents the number of threads. This method overrides the settings configured in the simulation file.

      Example Command Line Usage:

      • Windows (for CHARGE simulation using 8 threads):

         

      cd \path_to\simulation_file\
      "C:\Program Files\Lumerical\v232\bin\device-engine.exe" -t 8 "simulationfile.ldev"

      • Linux (for HEAT simulation using 8 threads):

        cd /path_to/simulation_file/
        /opt/lumerical/v232/bin/thermal-engine -t 8 "simulationfile.ldev"
