Accessing External Material Models for Magnetic Simulations
Characterizing magnetic behavior is crucial when designing magnetic devices involving ferromagnetic materials. Different materials (or the same material after certain processes) can react differently to the same stimulus and improper characterization can cause device failure. COMSOL Multiphysics® software version 5.2 expands the current support for describing magnetic materials and defines access to material models through external routines. Here, we demonstrate how this new functionality works in a case featuring hysteresis and review the current opportunities for modeling ferromagnetic materials.
