[Getdp] Symmtry problem

[gilles quemener]

Hi, 

Currently I am trying to formulate and solve a magnetostatic problem using the scalar potential method. 
This problem is sketched on the attached picture. I have some difficulties finding how to formulate the boundary 
conditions when simulating only 1/8 of the problem. 

For the Z = 0 plane it's fine w/ Neumann BC,i.e.t nothing in the formulation. 
For the Y = 0 plane, I use Dirichlet BC with null scalar potential. 
My problem is how to express the anti-symmetry : upward field / magnetization in permanent magnets on X>0 
and downward direction in the X<0 half space. 
I have tried to require null scalar potential on plane X=0, but the answer does not look correct. 
Without any condition on this X=0 plane, I also get incorrect results. 
Could it be only null scalar potential on the Z-axis ? Then I am a bit confused. 

Thanks for any help, 

Gilles
