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.

Before "fdtd.run() "

you should be able to see the FDTD file, and save it to a fsp file on you local machine. Then directly run it on your local computer, and then move to the cluster and run it. If the cluster has GUI you can open and run the file. If not, please refer to this link: https://optics.ansys.com/hc/en-us/articles/360024974033-Running-simulations-using-terminal-on-Linux 

You can also use one of the online examples with port objects, such as this one  https://api.lumerical.com/app-gallery/fetch-download-web?id=c118296f-waveguide-crossing 

run the example file on the cluster and try to get the result. See what happens.
