Finite Element Method for Solving the Screened Poisson Equation with a Delta Function

Finite Element Method for Solving the Screened Poisson Equation with a Delta Function

This paper presents a Finite Element Method (FEM) framework for solving the screened Poisson equation with a Dirac delta function as the forcing term. The singularity introduced by the delta function poses challenges for standard numerical methods, particularly in higher dimensions. To address this,...
