Multilevel-Atomic Susceptibility in 3D

[urbanmur]

Hi,

first of all I would like to thank everybody who is contributing towards MEEP, I've been using it for my research for quite a while now and find it extremely useful and simple to use.

Anyway, recently I am working on lasing in anisotropic systems and I wanted to use Multilevel-Atomic Susceptibility in 3D to simulate all 3 components of the electric field. However, already in the tutorial case as soon as a I call "dimensions = 3", I see no lasing. I believe I have set all the other parameters to appropriate values to work in 3D (I have done this before).

Are MultilevelAtom materials at all supported in 3D or am I missing something during the setup?

Thank you in advance!
