  2. Execute the command to run the software + &
    /opt/lumerical/mode/bin/mode-solutions &
    /opt/lumerical/fdtd/bin/fdtd-solutions &
    /opt/lumerical/interconnect/bin/interconnect &
    /opt/lumerical/device/bin/device &
    
  3. Run the command again on the same terminal window to open another instance of the software.

MacOS

    "/Applications/Lumerical/INTERCONNECT/INTERCONNECT.app/Contents/MacOS/interconnect" &
    "/Applications/Lumerical/DEVICE/DEVICE.app/Contents/MacOS/device" &
    
    
  3. Run the command again on the same terminal window to open another instance of the software.
