I tried the following coding to verify the source power, some errors were
encountered.
Meep 0.20.1 is being used with Guile v1.8. By the way, the Meep 0.20.1 is
running well for
other simulations now.
==============
(set! eps-averaging? false)
(define-param th 1)
(set! geometry-lattice (make lattice (size (+ th 4) (+ th 4) (+ th 4))))
(set! geometry (list
(make block (center 0 0 0) (size 2 2 2) (material air))))
(set! sources (list
(make source
(src (make continuous-src (wavelength 8.1)))
(component Ey)
(amplitude 1)
(center 0 0 0)
(size 0 1 1))))
(set! pml-layers (list (make pml (thickness th))))
(set! resolution 10)
(print "flux = " (meep-fields-flux-in-box fields x (volume (center 0 0 )
(size 0 10 10))) "\n")
(run-until 100)
===============
The error msg is following
