Description
This course is all about learning Multiphysics coupled simulations in COMSOL Multiphysics. It covers electromagnetic analysis, electrostatics, electromagnetic loss calculation, coupled electromagnetic-thermal analysis, electromagnetic-structural analysis and finally, various aspects of magnetic material non-linearity modelling.
An E-core transformer example is used for modelling. The course is structured in the form of simple tutorial videos demonstrating how to extract magnetizing and leakage inductances, parasitic capacitances, FEM-circuit coupling with rectifier and filter, iron and copper loss calculation, thermal analysis, structural analysis and BH curve modelling.
Each consecutive tutorial builds up on the previous step to develop a comprehensive capability for performing multiphysics simulations.
