GetDP, cyl.axis

could you help me how to define a correct constraint (Br=0 ?) for cylindrical symetry ?
If I define 0.0 on axis for vector potential, it is incorrect because of singularities, solution
is discontinuous. A[0]=lim A[r->0] would be correct.
Well, maybe I'm wrong and it's not possible to do it, but I don't like having A=0 on axis,
the only idea I have now is to increase mesh density near axis.


P.S. I like new versions of gmsh and getdp very much, much things seem to be improved.
Great work !
