Hi,
Does anybody know how to set a courant number? I know its default value is
0.5 but if you model a dispersive material then you have to set the courant
number as well.
Its formula is: minimum refractive index/squrt (number of dimensions). I am a
little confused. My computational cell is:
(set! geometry-lattice (make lattice (size 4 4 4)))
so what should be the value of the courant number?
Thanks.
Regards,
Hogen
