[SOLVED] MagnetoDynamics WhitneyAV: zero electric field

I am trying to get a simple solution for electromagnetic field generated by conductor with an alternating current. For some reason in case of transient solver it results in zero electric field and zero current in conductor, although magnetic field seems to be ok. The current is supposed to be set by...

Re: Scalar potential BC, WhitneyAVHarmonicSolver

Hi Peter, That's it! I have decreased the convergence tolerance to 1e-12, it works as it should be now - take a look at the picture below. I greatly appreciate your help. Selection_346.png The solver section now is: Solver 1 Equation = "MGDynamics" Variable = P[P re:1 P im:1] Procedure = &...

Scalar potential BC, WhitneyAVHarmonicSolver

I have got quite surprising result setting up a scalar potential difference at the ends of conductive wire for high frequency and WhitneyAVHarmonicSolver. To my opinion, it looks incorrect. The problem with a mesh and solution can be downloaded here https://www.dropbox.com/s/zwr6jndq8ou84zl/HarScalP...

Re: Definition of magnetic properties (MagnetoDynamics2D)

Thank you for help! Does it make any sense to try expressing analytically the relative permeability as a variable depended on magnetic flux density? Something like Relative Permeability = Variable b re, b im MATC "..." I am trying to involve MATC into business, because of a possible implem...

Definition of magnetic properties (MagnetoDynamics2D)

Hi, I am stuck in attempts to get the equivalent simulation results for the three different ways of magnetic permeability definition. Specifically I am struggling with the specification of H-B curve with MATC. Definitions via Relative Permeability and H-B table seem to work fine and produce the equi...

Re: integration over the axisymmetric bodies

Thank you Peter, I will definitely try to use MagnetoDynamics2D for these purposes. Am I right, that it is possible to use it with cylindrical coordinate system? Documentation says for MagnetoDynamics2D "Furthermore, an additional solver may be called to produce the magnetic field intensity fro...

Re: integration over the axisymmetric bodies

Hi Matthias, thank you very much for your promt reply! I have taken a look at the SaveScalars documentation. It might be I do not understand all the possibilities completely, but I can see some obstacles on a way to magnetic field energy estimation with StatMagSolver+SaveScalars: - StatMagSolver pro...
