Description

This LS-DYNA simulation shows a simple Electromagnetic forming example using the EM solver. A R,L,C circuit is defined in the coil which produces induced currents in the workpiece. This in turn generates Lorentz forces which cause the plate to move. Local heating is also produced and handled by the thermal solver. An EM EOS couples back the temperature to the Electromagnetic solver by making the electromagnetic conductivity temperature dependent. The FEM and BEM matrices are recalculated every 20 timesteps in order to save calculation times. Coupling between EM and the thermal and mechanical solvers is automatic (no extra keyword mandatory).
