Abstract

A finite-volume Maxwell solver in cartesian coordinates was developed as a part of a 3-D transient MHD code MAPS. The code is capable of solving a broad class of magnetoquasistatic electromagnetic problems with moving conductors. A Coulomb gauge is easily implemented by imposing a numerical constraint on boundaries of the computational domain. To simulate problems with moving conductors, a new boundary condition for electric scalar potential on the current source surface is used. The presence of the electric scalar potential in the formulation ensures current conservation in the MAPS solution. The results of MAP3 benchmarking against 3-D finite-element code MEGA are presented
