@rahul.sanghvi,

To run Python API will require a GUI connection and a GUI license. >>Python API overview – Ansys Optics

If you do not have a GUI connection (headless Linux system); 

• Consult with your IT/cluster admins to: 
• Install or configure the MPI - used to run FDTD simulations (.fsp) with Lumerical 2024 releases >>Running simulations with MPI on Linux – Ansys Optics 
• Configure your environment for Lumerical API >>How to run Lumerical API scripts from terminal in Linux – Ansys Optics 
• And run with virtual display >>Running CAD jobs on headless Linux systems – Ansys Optics<<
  • Where on the newer versions you simply set QT_QPA_PLATFORM=OFFSCREEN and run the API (.py) script. 

Hope this helps.
