What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...

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?
