Resistive Heating and Battery Modeling

This course is based on the Electromagnetics (EM) solver of LS-DYNA. The EM module computes the Maxwell equations and is embedded into LS-DYNA following LST LLCs one-code strategy, thereby allowing for an efficiently coupling to the solid-mechanics and the thermal solver.

The seminar presents the solver’s general principles, a complete keyword description for setting up simulation models, on the one hand, to compute inductive and resistive heating problems. On the other hand, the modelling of batteries is addressed. Thereby exploiting the Randles-circuit approach to describe the charging and discharging process as well as the accompanying heat production.
