I'm quite new here: What is FEMM 3D?

Hi Vidar,

Thanks for your previous answer, and your idea is different from that of Stefan indeed, I agree.  Unfortunately, these arrangements in 3D are difficult to judge in one's head whether they work or not.
Here would come into the picture some magnetic simulator software programs like FEMM.  Unfortunataly, there is no FEMM 3D but 2D.
As Aerny wrote it is Finite Element Method Magnetics and it is freely downloadable from this site:

The true 3D magnetic simulator programs are very, very expensive (like Maxwell from Ansoft, for instance (www.ansoft.com) and there some others from different firms too.

Thanks for your reply I will try to use FEMM 2D then and imaging the 3rd dimention...

   Here in lies a very hard problem. You cant sim a 3d world in 2d. It seems that many will still try no matter how you tell them. Then you hear how the simulation doesn't agree with the stated actuality. Only on a bench will you be able to tell the truth to the matter. Sim software is great as long as it is used in the constraints that it was programmed with. If you work in 3d, then sim in 3d.
