About mesh multiplier in MODE
I am trying to simulate this example recently: Edge coupler – Lumerical Support
In the Script file of the no substrate case, (file name: Edge_Coupler_No_Substrate.lms) they are using codes to add taper structures. However, when they are adding the Si substrate override mesh, they used these two lines (line 158 and 159) of codes which cannot run on my computer.
set("set mesh multiplier",true);
set("z mesh multiplier",4);
May I ask what is the meaning of these two lines? Are they important for this program?
Many thanks in advance!
