The problem Emmanuelle has here really is solving an anistropic diffusion
equation on a big grid. This can be seen as a PDE problem. Do you have
any suggestions on good linear algebra or iterative options to do this
with Python? We have not looked at FiPy so far, as it seems tedious to
formulate the problem in PDE terms.
