We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

@Vincent Letourneau,

Can you open ‘fdtd-solutions’ directly from the terminal on the cluster? 

/opt/lumerical/v241/bin/fdtd-solutions &

If so, then you can run the python script from the GUI. Try running the sample script that is shown in the image below. 

You can run the simulationfile.fsp directly from the terminal.

e.g. run with 32 threads on the machine (-t 32)
/opt/lumerical/v241/bin/fdtd-engine -t 32  simulationfile.fsp
