[Getdp] 3D magneto static problem

[svhb at telenet.be]

Hi,

Doing some initial tests with gmsh/getdp, I have a problem to make convergent calculations. GetDp stop every time after 1000 iterations. Some B-vectors are scattered around (see attached picture).

Probably there is something wrong with the formulation. The Magsta_a_3D.pro file is a modified version of the MagSta_a2D, ...

The model is a simple U-shaped core with solenoid, sitting against a metal plate with an air gap of 1mm.
I did the same model in 2D with more success. 

For the mesh, I just press 2D, the 3D, then optimise(Netgen) and then save. I tried already with finer meshes, no result.

Does someone has 5 minutes to have a look at my files, I'm struggling already some time with this. 


Thanks very much.
Stefaan
