I am trying to use the frequency-domain solver for a 3D problem, 25x25x22 with
resolution=10. The output from
(meep-fields-solve-cw fields)
is:
Meep: using complex fields.
on time step 1 (time=0.05), 41.9989 s/step
final residual = 0
Finished solve_cw after 1 steps and 0 CG iters.
It seems that nothing is done, taking 42 sec. I think that the way to see the
waveform at a point is:
(run-until 10
(to-appended "ex"
(at-every 0.05
(in-point sample_point output-efield-x)
)
)
)
and this gives the same result - i.e. the solution starting from 0 - as if I
had not previously invoked meep-fields-solve-cw.
I have seen other posts on the mailing list on this subject, but I have not
been able to find any resolution. It would be very helpful to have an
explanation of this apparent problem. Does the frequency-domain solver work?
Thanks
Gib
