I have a error for 1d bragg grating using epsilon function
when I had setting : (set-param! dimensions 1)
(define (f p) (+ 2 (sin (vector3-x p))))
;(set-param! dimensions 1) ; in this caseis -> it occured error( eps profile not a
;(set! geometry-lattice (make lattice (size 10 0 no-size)))
(set! geometry-lattice (make lattice (size 10 no-size no-size)))
(set! geometry (list
(make block (center 0 infinity infinity ) (size 10 infinity infinity )
;(make block (center 0 0 0 ) (size 1 0 0 ) ; this is iput -> occure error in eps
(material (make material-function (epsilon-func f))))
))
(set! sources (list
(make source
(src (make continuous-src (frequency 0.15)))
(component Ey) (center -5 infinity infinity))))
(set! pml-layers (list (make pml (thickness 1.0))))
(set! resolution 10)
(run-until 200
(at-beginning output-epsilon)
(at-end output-efield-y))

;run 0 finished at t = 200.0 (4000 timesteps)
it wa ok but 2D!!!
so I had rewrited
(define (f p) (+ 2 (sin (vector3-x p))))
(set-param! dimensions 1) ; in this caseis -> it occured error( eps profile not a
;(set! geometry-lattice (make lattice (size 10 0 no-size)))

block, center = (0,1e+20,1e+20)
size (10,1e+20,1e+20)
axes (1,0,0), (0,1,0), (0,0,1)
meep: Cannot split 0 grid points into 1 parts
it was 1D but error occured
what's wrong ???
