### calculate displacement with maxwell stress (mgdyn)

Posted:

**21 Jul 2016, 17:03**Hi!

How is it possible to get the displacement caused by the magnetic forces?

I have the maxwell stress tensor and the nodal forces. First problem: But I don't really know which element of the stress tensor in elmer (numbered from 1-6) belongs to which element in T_x,x ; T_x,y ...

Second: it is possible to set elmer a stress tensor as a body force, but when i try to set it equal as the maxwell stress tensor i get only a the trivial solution.

Thank you in advance
