Line with dipole moment density

I'm new in Comsol.
Is there way to add line with some dipole moment density to stationary electric current model.
I've tried Parametric Curve + Line Current Source
but it probably cannot be used in stationary model
Error message is:
"Failed to find a solution: Very ill-conditioned preconditioner. The relative residual is more than 1000 times larger than the relative tolerance. Returned solution has not converged."

Problem is same if one wants to give dipole moment density to 2D boundary or 3D domain.
Only current source, not dipole is choosable.
Also, I think would it be possible to give dipole moment density to single tetrahedron of the mesh, but I don't find way to this, either.
