Dear Pawel,<br>
<br>
Here are the corrected files for your h-conform magnetostatic
formulation. You will see that the fields Group (Dirichlet_h, Domain),
Constraint (for both magnetic scalar potential phi and source field
hs), FunctionSpace (for hs) and PostProcessing (b=mu*(hs+grad phi))
have been corrected.<br>
<br>
It is possible to compute the source field prior to the scalar
potential. In this way, the equations gathered in your formulation can
be decoupled, which gives two systems of equations of lower size to be
solved. There is a way to do that easily for any number of inductors. I
will explain and illustrate the technique with an example soon.<br>
<br>
Kind regards,<br>
<br>
Patrick<br>

software to solve this problem. I have tried to create and solve simple
examples of magnetic field problem. I have had no problem with 2D
examples but in 3D examples I have encountered many problems. The
results of calculations of extruded 2D problem (b-conforming) are very
strange, differ between themselves considerably. I tried to solve the
same 3D problem with h-conforming formulation, and “Iterative solver
has iterated too many times”. <o:p></o:p></font></font></span></p>
