Hi again, last night I tried a lot of things with the sphere, but the results are getting worse than before. One problem is, that I do not really manage it make a fine mesh in the copper-cylinder without getting memory troubles and all other meshing solutions e.g. extrusion 3D, netgen on 2D and 1D w...

Thanks, I will try the sphere air volume.
I thought I would help the solver if I use a cylindric air, due to the radial magnetic field. Additionally, I added a very small mesh in the middle due to my small copper thickness (10 mm) in comparison to the big conductor diameter with 330 mm.

Hi, I added the Salome-File and removed the mesh. I did a transient simulation with a DC-voltage on its input (2.8923e-04 V) and received approx. 26 A, which matches the theory. But when I add a sinus-function, the H-field-vector is not only in the wrong direction, the magnitude is also nearly 0 A. ...

Dear all, I'm currently trying to simulate the transient magnetic field and current density of a cylindrical waveguide and noticed something strange. I applied a sinusoidal potential (50 Hz) on the first boundary and ground to the second boundary. Then I used SaveScalar to calculate the current at t...
