Greetings, I want to know if theres any particular way to calculate what "Courant factor" one should use to get stable output.
I was using the default courant number in meep for two cases: Case 1: "a" = 100 nm with resolution 5 for vacuum wavelength corresponding to 850 nm Case 2: "a" = 1 micron with resolution 10 for vacuum wavelength corresponding to 850 nm The output blows out in case 2 while it is stable in case 1. I wonder if theres any systematic way by which i can fix the range of my "courant factor < (n_min / sqrt(#dimensions)" OR should I go with trial and error method till I get stable output Any suggestions would be of immense help. Regards Triratna
