Multiphysics Simulation

by Jose Alves

As demonstrated in the previous sections, Computational Electromagnetics (CEM) is crucial not only for understanding electromagnetic (EM) wave propagation phenomena but also as a fundamental physical building block for multi-physical applications.

In the field of structural mechanics, numerous applications can be identified, including electric motors, electromagnetic propulsion systems for Maglev-like transport devices, actuators, and magnetic latches. Additionally, the integrity of electrically conductive assemblies, when subjected to simultaneous mechanical and electrical loadings, is another significant application.

In material forming, EM methods are typically employed to control fluid flows, particularly when the liquid is conductive, as seen in the continuous casting of molten metals. EM is also used to shape thin solid parts by exposing them to rapid magnetic pulses. Additionally, EM techniques can locally alter material properties through Joule heating, as employed in induction hardening processes.

EM multiphysics applications are also prevalent in electrochemical contexts, such as the charge and discharge processes in batteries, which are crucial for estimating the lifecycle of electronic devices.

In summary, the potential applications are nearly limitless. The numerical methods we have discussed previously have emerged as a fundamental third pillar of science and engineering, complementing theoretical analysis and experimental verification. They play a crucial role in deepening our understanding of complex, coupled phenomena and facilitate a swift transition from theoretical frameworks to practical applications.
