Unbounded Axisymmetric FEM Formulation for Static Fields

This paper describes an unbounded approach for solving the Poisson equation by the Finite Element Method (FEM). With domain mapping, it is unnecessary to truncate the domain at an arbitrary distance, where the potential is assumed negligible. The formulation herein has applications for static fields, has a simple implementation, and can handle infinite heterogeneous domains, which is a limitation of several FEM software. Such an approach raises the simulation precision and can save computational resources.
