3D Magnetostaticswith two Supermagnets

Post by chouonrow » 28 May 2019, 20:08

Hello! I have almost ready to show you a case that could be helpfull for more people. It looks like this
(188.97 KiB) Not downloaded yet

The problem is that I still have problems solving it. I have few questions that maybe somebody could help me with:

1. For a case like mine where I just want to see the Magneticfield lines /intensity etc... is it enough with the "Air" volume?.
2. My main problem is the solver. I have followed the tutorials, I did the 2D one for a permanent magnet and it worked perfect. But the "Magnetic field induced by harmonic current in a wire", doesn't help a lot since there is no WhitneyAVHarmonicSolver. So I guess I can use just MgDyn and MgDynPost and should work the same way?
3. What else am I missing? To be honest, I am quite new with Elmer and the learning curve is quite huge.

My set up is 2 small permanent magnets separated (and each divided in 2 volumes to be the + and -) and also a bigger volume where the "air" should be and we see the Magnetic field.

Thank you!

You might try a finer mesh (smaller elements), most FEA tools a dependent on mesh size for good results.
