I'm looking for software recommendations for an electrostatic simulation:
I have a 3d object of uniform, high conductivity, separated from its environment by a high-resistance skin. Inside that object is a dipole, and I want to calculate the strength of the dipole's generated electric field on the surface of the object.
I've been working with a colleague's old thesis, in which he develops an approach to solve for the field using FEM/BEM. I've coded up his BEM solver in Matlab, but it's quite slow to run, and I'm not convinced I'm getting the right answer. I wouldn't be surprised if there was a tool for this already out there, but I haven't had much luck finding one so far. Any suggestions? I already have the mesh (which has ~3300 vertices, though I can edit this), I just want to pop it in with some conductivities and a dipole location, and get back the field on the surface of the mesh.
(For those curious: I study a species of fish that generates electric fields, and uses perturbations in these fields to detect objects in its environment; I want to do some simulations to get a better sense of what the sensory signal at the skin actually looks like.)
