Moving Mesh Not Converging

Please login with a confirmed email address before reporting spam

Hello, I'm running a multiphysics fully coupled simulation with solid mechanics and magnetic fields, Using the maxwell stress tensor as boundary stresses. Because of the solid mechanics, the instrument is deforming and therefore should change the magnetic field around it. For this i'm tring to use moving mesh, but unfortunately the solution doens't converge and I don't really know why. I'm attaching the convergence plot and and the .mph file The solid mechanics and moving mesh alone does converge as long as the maxwell stresses doesn't applied as boundary load.

Thanks in advance, Jonathan
