As computational power has increased, companies have started incorporating multiphysics models into their analyses. JMAG began offering this functionality to its users in 1994, when magnetic field/thermal coupled analysis functionality was implemented for induction heating device design. Since then, a considerable amount of development has taken place in the area of multiphysics.
With such a large variety of analysis domains and the complexity of modeling within each domain, JSOL has formed partnerships with CAE vendors in each analysis field with the goal of providing an easy to use platform from which to embark on multiphysics modeling.
High-Frequency Induction Hardening of a Gear
This is an example of high-frequency induction hardening of a gear. Heat is generated as eddy current is induced near the skin of the gear due to harmonic currents of the heating coil. Heat generation acquired through eddy current analysis is passed on to the element face of the thermal analysis model as heat source of the surface, after it has been integrated in the thickness direction. By using the conversion function from volume data to surface data, eddy current accounts for the skin effect and also avoids unnecessary mesh divisions near the surface for thermal analysis. As a result, the analysis has become more efficient.
Centrifugal Force of a Motor
Stress from the centrifugal force acting upon the rotor is evaluated.
JMAG's capability of stress calculation in one magnetic field analysis realizes constant multifaceted evaluations. Multiple disciplines are closely integrated in JMAG and can easily incorporate multiphysics analysis in your daily analysis work.
Magnetostriction is one of the major sources of vibration and noise. This example visualizes vibration induced in a large transformer as well as sound pressure distribution in the surrounding area (on the sphere) based on magnetorestriction distribution results.
