I am trying to run a cylindrical coordinates simulation with

radius.
The structure involved is a ring, so all of the field is close to the
outer perimeter of the cavity.
To save time I would like to define the
computation domain over (rmin,rmax) as oppose to (0,rmax).
Is that possible to do?
Yes. At least, this feature worked at one point, but it's been awhile
so you might want to test it carefully on some simple cases to make
sure it's working.
You have to call a function fields::set_rshift(R) to shift the
starting radius in the computational cell from r=0 to some other
radius R. In the Scheme interface, you would do:
(init-fields)
(meep-fields-set-rshift R)
before calling (run) or anything like that.
