electromagnetic forming simulation

Hi.
how can we couple electromagnetic forming simulation with structural mechanics and it is possible to show the deformation in workpiece due to lorentz force distribution.

Hi

Well if I understand you right you have current densities from the EM (ACDC i expect) and magnetic fields, hence you can get the lorentz forces i the volumes/sections, that you should be able to couple as volumic forces in your structural model subdomain BC's no ?

Perhaps you need to add the B*B term for the iron in your circuit too ?

I believe there are some models out there or in the doc, just cannot come up with one like that just now

Good luck
Ivar
