I am currently taking UBCx: Phot1x Silicon Photonics Design, Fabrication and Data Analysis on edX.
After installing Lumerical MODE, I tried to run an example of “Y Branch”. I stepped through the example of the tutorial video and the software crashed when I try to do material check (step 7).
GDS Layout import of the Y-Branch geometry; material settings
VarFDTD solver; simulation volume; PML boundaries;
Mode source at the input waveguide; wavelength settings
Check slab mode profile in varFDTD, as in the Effective index method Mode
source profile Monitors;
frequency-domain field and power in output waveguides
Check “core” effective index of slab waveguide
Run 2D FDTD simulations
Visualize transmission versus wavelength
I tried to skip material checking (step 7) and tried to run the simulation (step 8) but the software crashed as well.
I tried to skip material checking (step 7) and running of simulation (step 8) and save my profile file but the software crashed as well. So I was unable to send a profile file to you.
I attached the Y branch GDS I downloaded from the course for your reference and below are the message I got when the software crash:

One more piece of information. I was actually able to run the script provided by the course on Y branch (attached). However, I was unable to reopen the output files (attached) without running the script again. Hope this information is useful for Lumerical to help debug my issue.

Thank you and Hope I can get a solution as soon as possible.
