Multipole expansion for the 3D periodic Green
WebThe Multi Level Fast Multipole Method ( MLFMM) is part of the integral equation solver. It is a fast and efficient method, which scales very good for electrically large models … The fast multipole method (FMM) is a numerical technique that was developed to speed up the calculation of long-ranged forces in the n-body problem. It does this by expanding the system Green's function using a multipole expansion, which allows one to group sources that lie close together and treat them as if they … See more • Barnes–Hut simulation • Multipole expansion • n-body simulation See more • Gibson, Walton C.
