Hello! I have almost ready to show you a case that could be helpfull for more people. It looks like this
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!
The problem is that I still have problems solving it. I have few questions that maybe somebody could help me with:3D Magnetostaticswith two Supermagnets

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

This case is helpful
"Attached is the case in somewhat modified form. The same case is now done both in 2D and 3D, and we even obtain same results. I compared to an analytic formula but it is accurate only when x>>R. In this case we have x=2R. Already with x=4R the relative error is reduced to about one third. Maybe you will find better references.
I hope this helps people dealing with permanent magnets.
