emag3EMAG is the electromagnetic module of the general-purpose finite element-based program NISA. It can determine electric and magnetic field distributions in a wide class of electromagnetic devices. EMAG performs electromagnetic analyses by solving the appropriate Maxwell's formulations. It is coupled with NISA/HEAT to enable a coupled analysis of electromagnetic and thermal fields.
