Re: Strange problem with MgDyn-Solver
The air volume in paraview can be turned off and one by using the threshold filter, filter on geometry IDs, you can filter to only show the bodies you want to see. In the run I posted I had put voltage on the outer skin, and ground on the inner skin. I will re-run with voltage on the end. I tried me...

Re: Strange problem with MgDyn-Solver
My mesh was very different, generally with magdyn the part is placed in a volume of air, preferably a sphere since the far field boundary is tangent to the surface. farfield.png cylinder.zip If you look at the elmag examples they are generally done this way. https://github.com/ElmerCSC/elmer-elmag

Re: Strange problem with MgDyn-Solver
Looks OK to me. The magnitude of the magnetic field in Paraview appears to be always a postive number, but the components x, y, z oscillate. I used your sif, but I had to build the mesh.

Re: High order infinite loop during partition/ parallel run fails
Have you considered p elements as an alternative to higher order node elements.

Re: "Explotion" inside a metal box
Your flow appears to be very turbulent which can be a challenge in Elmer.

Re: Error using CoilSolver
I may have mixed up the coil and the core in my sif, need to verify the bodies.
Also use the elemental results, the ones ending in e.

Re: ElmerGrid weirdness
They are boundary elements so if you do not target those boundaries in the sif file and impose boundary conditions on them they will be ignored by the solver. Same with bodies, if you do not create the body in the sif, a body in the mesh will be ignored.

Re: electrodynamic forces on busbars
This project couples magnetic force to displacement, although the magnetic field is not electrical induced
but you should be able to go from electrical field to magnetic field to mechanical force
