[Getdp] issue with 2D axisymetric solenoid magnet resolution

Hi Frederic,
The problem came from your geometry: the physical line for the symmetry and infinity where you define the dirichlet boundary condition was not properly defined.
You have to use the geometrical lines and not the loops.
See the small correction in the geo file. 

Best regards,
Ruth
