Abstract A finite element approximation is proposed as solution of the Neumann problem for the Poisson's equation Lu = f, where f represents a dipolar source. The solution is searched in the form u = v + u0. The term u0 is the fundamental singularity of u defined in a small neigbourhood of the source, where anisotropy can be consider uniform, and null elsewhere. Numerical results are presented and discussed.
