Where can I find free electric field simulation software for Mac OS X?

[nuiluidwde]

Hi,

I'm looking for some free electric field simulation software, ideally it should support Mac OS X, or at least be open source so I can compile it for Mac, but finding a linux or windows pc isn't difficult for me. It should be able to take an environment filled with charged objects and give the electric flux at different points, preferably as a colour map, but also giving the value at given points or as a graph. Magnetic fields and charged particle trajectories would be nice, but I don't need them.

Does anyone know any software like this out there? I have found a couple modular physics simulation software out there, but they either cost a lot or the price has to be negotiated. I don't want to pay for this software, but I could make an exception if it is fairly cheap.

Thanks :)

Something like this, but supporting electric fields, is kind of what I'm looking for:- http://www.mare.ee/indrek/ephi/, or this but commercially/freely available:- http://www.integratedsoft.com/products/coulomb/default.aspx

Also, something like this:- http://www.sci.utah.edu/~gk/phys340/software/xphysics.html which is free but not open source, would be acceptable.
