Reply To: Lumerical fdtd-engine failing quickly with Hangup error on Linux

[Lito]

There is a known issue with R2.3 on Linux when running with out a GUI connection or X forwarding. This issue should be fix in an upcoming release. Can you try to download and use R2.2 using the link, Lumerical-2021-R2.2-2806-df9013d.tar.gz (expires Nov 04 2021 17:34UTC):https://go.lumeri.ca/64dcr. Otherwise, for R2.3 run the simulation job from the FDTD CAD/GUI if you allow running the GUI in the cluster.
