@schinta3,

Our API/scripting environment is part of the CAD/GUI and will always require a GUI interface/connection to the machine running the API/script. 
>>>Lumerical product components and licensing overview – Ansys Optics 
>>>Python API overview – Ansys Optics 

We recommend running this from the Lumerical CAD > script editor window on a machine with a GUI interface/connection. 

Otherwise, a workaround would be to run with Xvfb (virtual display). *Take note that this workaround is provided as is and might not work for certain Linux installations.
