Hello,
there have been a series of reports about divergence when running 3D
simulations applying symmetries. The first one was http://article.gmane.org/gmane.comp.science.electromagnetism.meep.general/1590/match=
. I also noted a similar issue, basically the simulation seems to
diverge when eps averaging and the symmetries along the three axis are
used, while it runs fine when only symmetry along Y and Z directions
and eps averaging are imposed. Is this the problem you are facing? Do
you have any suggestion to overcome it?
Bye,
Alessandro

Hi Marko,
I have also noticed that the 3D simulation is unable to converge if
symmetry planes are used. I do not why and would be happy to learn.
Bloch boundary conditions work fine for me. Hopefully you can use them
as well.

Hi,
I'm using a Cartesian coordinate system and have a symmetric
structure
in 3 dimensions: planes of symmetry are XZ and YZ and it is also
symmetric under rotation for 90 degrees about Z axis. Sources are
specified as XY plane.
I wonder why the simulation does not converge when polarization of
source is in Ex and two symmetry planes are specified, one with phase
1 (normal direction is Y) and another with phase -1 (normal direction
is X).
I also wonder how it would be possible to use rotate4-sym (fourfould
symmetry), what should be the polarization of the source and the
phase
factor for symmetry.
Thanks
