Investigate the consequences of Helmholtz’s theorem when applied to Maxwell’s equations, and when using scalar and vector potentials to represent physical fields.
COMSOL 4.4: Magnetic Saturation Curves at your Fingertips
December 2, 2013
When designing inductive devices, both challenges and possibilities are associated with the nonlinear behavior of ferromagnetic materials. COMSOL Multiphysics is well-adapted to the solution of highly nonlinear numerical models but high-fidelity modeling of nonlinear inductive devices also requires accurate material data. To meet this challenge, a library of 165 nonlinear magnetic materials is provided in COMSOL 4.4, bringing new powers to the design and modeling of electric motors, transformers, relays, etc. Here, we will discuss how the modeling process is […]
