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
