A finite element approximation is proposed as solution of the von Neumann problem for the Poisson equation $Lu=f$, where $f$ represents a dipolar source. The solution is searched in the form $u=v+u\sb 0$. The term $u\sb 0$ is the fundamental singularity of $u$ defined in a small neighbourhood of the source, where anisotropy can be considered uniform, and null elsewhere. Numerical results are presented and discussed.

Abstract
A finite element approximation is proposed as solution of the von Neumann problem for the Poisson equation $Lu=f$, where $f$ represents a dipolar source. The solution is searched in the form $u=v+u\sb 0$. The term $u\sb 0$ is the fundamental singularity of $u$ defined in a small neighbourhood of the source, where anisotropy can be considered uniform, and null elsewhere. Numerical results are presented and discussed.File in questo prodotto:
