[Getdp] Magnetostatic problem in 3D (non symetrical)

[Patrick Dular]

Palo,

I have just posted to the getdp wiki a 2D and 3D magnetodynamic 
formulation in which stranded and massive inductors can be taken into 
account. A complete example of application is given as well. In the next 
future, I will post a 3D magnetostatic formulation with stranded 
inductors. Such a formulation could be built from the magnetodynamic one.

Kind regards,

Patrick
