Hi, the suggested project is appealing to me because it seems it could greatly simplify installation procedure of MEEP at Windows. I can imagine convincing many colleagues at the institute to run FDTD simulations when their computer is idle... However, not knowing anything about NaCl, I am still concerned about the performance; usually one wants to compile MEEP from sources to get the optimized code for their particular architecture. On the other hands, if whole MEEP is compiled before being run, quite a lot of external dependencies will have to be packed. So far, it is possible to run a simulation of sodium chloride in MEEP, but not vice versa. How should a typical scenario of MEEP under NaCl look like? F.
