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.

Hi Devika, it crashes at a different spot each time with no consistency. I've attempted to run a similar y-junction program, the inverse design, and it is crashing in the same way also at different spots. For some reason, the 3D FDTD runs fine without crashing but I cannot get the 2.5D varFDTD to complete an optimization run. I have also tried running the varFDTD ring resonator example, and the program crashes when trying to run both the nested parameter sweep and the Monte Carlo analysis. However, I have created a straight waveguide file to test the varFDTD solver, and it was able to complete a regular parameter sweep of y_span vs T. Any help you might have would be greatly appreciated, thank you!
