Boudary conditions for 2D modelling of superconductors with in plane currents

I am trying to model the current distribution along a superconducting cable. I am using the general PDE module so I can get away from the problem of circular dependency of conductivity and the current by calculating the magnetic field distribution and then calculating the current from that. This works well with the current perdendicular to the modelled plane but I am now trying to model the current in plane either as a slab or as a wire using 2D-axial symmetry. With the current in plane I either get the error message "may have reached a singularity" or "recoverable error i n residual, but solver could not recover".
Has anybody successfully built a similar model? What boundary conditions could I use to allow the solver to converge?
Thanks.
