It was really helpful.
I have struck on one more problem.
I am doing simulation in which the propagation direction is 11 micrometer. When I am running the simulation the auto shutoff level is going too high and Lumerical is showing error (Diveging Field). I have gone through all the possible solution given on the website but still I am not able to solve this problem.
I am using SCPML boundaries with 12 layers and auto no-uniform mesh with min mesh step 20nm.
Looking for your reply.
Thanks In Advance
