The Finite Element Method is a popular technique for computing an approximate solution to a partial differential equation. The MATLAB tool distmesh can be used for generating a mesh of arbitrary shape that in turn can be used as input into the Finite Element Method.; The MATLAB implementation of the Finite Element Method in this article used piecewise linear elements that provided a   grids.
