I have a problem with running varFDTD that extends beyond running my simulations that I have created myself. I try running var FDTD with Lumerical example files such as ring_resonator.lms and waveguide_coupler.lms and they won’t work as well. Here is what happens.
In most of the cases, after activating varFDTD solver and running it, the progress window shows up pretending that the structure meshing is being performed, and then running is being executed, but no progress is being shown. The window disappears after a few seconds - just like if the simulations were completed, but there is no simulation results: all the monitors show blank results window. Did anyone experience this issue? Is there something that I may be missing to run the simulation?
FDE mode solver works fine with both my files and Lumerical examples.
