Unfortunately, there is not much you can do besides increase the L parameter
and the number of iterations.
Increasing the diameter of a simulation relative to the wavelength increases
the condition number, which worsens the convergence of iterative solvers. The
general way to improve this is
Hello to the meep community,
I was hoping to use the frequency domain solver for my own application,
but I've encountered a stumbling block.
I've played around with the ring resonator tutorial example, and it
seems that when I increase the domain size (let's say a radius of 10
micrometers)
Hi Saket,
This is an error message sent by Guile because (meep-fields-solve-cw
fields tol maxiters L) is not called properly.
For example, this message appears if maxiters has type double instead of
integer.

Hi, Gib, perhaps I was a bit confused. The fact is that MEEP source
has been fixed by the commit I mentioned, and it was not before April
2014. Therefore if the release 1.2.1 comes from March, it is probably
not fixed (no matter

Dear MEEP users/developers
Is it possible to use MEEP's frequency-domain solver in the c++ interface?
If yes, what are the corresponding commands?
Thanks for your answer in advance,

Hello Ali,
you can use the solve_cw() function.
However you may have to fall back the norm2() in the CG-algorithm
of meep 1.2 to the old one, which was from meep 1.1 or earlier.

Hi everybody,
I was wondering if anybody managed to get some experience with the frequency
domain solver in MEEP.
I succeeded in getting my simulations up and running, but so far they all ended
in CONVERGENCE FAILLURE.
I don't know if there's any relevance to my problem, but if I output my
