Steven-
believe i found a minor error, but it's probably just numerics. in a
control file, place:
(define a 1)
(define sx (/ a (sqrt 2)))
(define sy (* sx (sqrt 3)))
(set! geometry-lattice (make lattice (size sx sy 10)))
(set-param! k-point (vector3 0))
(set! pml-layers (list (make pml (thickness 1) (direction Z) (side
Low)) (make pml (thickness 1) (direction Z) (side High))))
(set-param! resolution 32)
(set! sources (list (make source (src (make continuous-src (frequency
1))) (component Ex) (size sx sy 0) (center 0 0 -4.5))))
(run-until 20 (at-end output-efield-x))
running meep (either in linux or a mac), i get:
-----------
Initializing structure...
Working in 3D dimensions.
time for set_epsilon = 0.484472 s
-----------
meep: Source width > cell width in y direction!
replacing sy in the size for source, w/ (- sy 6e-3) avoids the
problem. of course, 6e-3 depends on the resolution used...
thanks,
gp
