I don't know of anyone who has successfully ported femm to run native on Linux. The best bet might be to try and recompile the source using winelib, which could work better than running the unmodified executables in Wine. Someone might have gotten it to work, but has it has been noted (see http://groups.yahoo.com/group/femm/message/999) if someone has been successful in performing a port, they might keep quiet about it because of licensing issues related to Microsoft...

More on 3D stuff in a later message.

The femm solver might be amenable to being modified for some sort of cluser computing. The solver is really a command-line application that is wrapped up as a Windows dialog application, and it would be easy enough to unwrap it to get a command-line C++ program that would run on just about any platform. In fact, in an older version of the program, the solver was a command line program (I changed it because I couldn't get a call to a command line program to behave the same on all installations of windows, leading to a lot of problems with things working fine on my machine, but not on some other machine running a different version of Windows.) I don't really know much about cluster computing, however, so it would be hard for me to say how it would have to be modified to be amenable to running on a cluster.

Dave.
