What is the difference between mathematical R^4 space and physical 4D unit space?

We assume that the difference is huge and that it is not possible to compare the two spaces. The R^4 mathematical space considers time as an external controller and the space itself is immobile in...

What type of EM simulations are you looking for? Most of the commercial EM-simulators will use some kind of a fast algorithm for solution acceleration.

Another alternative to FMM will be FFT-based methods like procreated FFT and AIM (adaptive integral method).

For example, if you are interested in magneto-quasi-static parameter extraction, FMM-accelerated FastHenry/FastCap solvers are the ones you are looking for.

Are you looking for a way to accelerate your own MoM solver or for a solver to solve some particular large-scale problem?
