Description

The finite element method is the standard approach for solving partial differential equations in geometries in which the boundaries are not simple variable ranges. This article illustrates the basic approach by solving Laplace's equation in two dimensions for a region consisting of two unequal rectangles joined together, for a Dirchlet boundary condition (function specified on the boundary).
