This unsteady/transient electromagnetic-thermal tutorial is based on a simple bar-and-coil induction heating co-simulation with two-way 3D data transfers. Maxwell performs an electromagnetic Eddy-Current analysis which is dependent on System Coupling time and Fluent performs a transient thermal analysis, while System Coupling coordinates the simultaneous execution of their solvers and the data transfers between their coupled volume regions.

Adaptive passes are used to generate and refine Maxwell's mesh. For every coupling step, Maxwell serves an updated mesh to System Coupling, which triggers Fluent to also serve a new mesh. System Coupling then remaps both participant meshes on the affected coupling interfaces. The resulting mapping is used for subsequent coupling steps and iterations until Maxwell provides another new mesh and the process is repeated.
