PhysicSolver is a computer program designed to solve two-dimensional problems of electrostatics and magnetostatics. Three-dimensional problems with a planar or axially-symmetric geometry can also be solved. The finite element method is used to solve the problems. The problems can include regions of any shape containing materials with either linear or nonlinear properties. In the case of nonlinear magnetostatics, a magnetization table is used to describe the nonlinear material. Saturation and ferromagnetic effects are taken into account. A problem defined in a domain that extends to infinity can be solved in a finite domain by placing an artificial boundary at some distance from the region of interest.
