Dear Arthur, thank you for sharing your code! I cloned your source, downloaded the meep 1.2.1 sources and copied your files over the original directory. Then I used my old compilation procedure on Ubuntu [1] to compile meep and rebuilt the python-meep interface.
The new functions of snapshot() and nf2ff() appear in the meep-mpi module. This looks promising. I will try out your functions using my Python scripts. There is a lot of functions that would make MEEP easier to use in some cases (so far I had to write them on my own). I have some code to contribute, would you be interested to extend the functions in your repository? (Of course the best practice would be to incorporate it in the trunk source!)
