Abstract
In this paper, we review the lowest order staggered discontinuous Galerkin methods on polygonal meshes in 2D. The proposed method offers many desirable features including
easy implementation, geometrical flexibility, robustness with respect to mesh distortion and
low degrees of freedom. Discrete function spaces for locally H1
and H (div) spaces are considered. We introduce special properties of a sub-mesh from a given star-shaped polygonal
mesh which can be utilized in the construction of discrete spaces and implementation of the
staggered discontinuous Galerkin method. For demonstration purposes, we consider the lowest
case for the Poisson equation. We emphasize its efficient computational implementation using
only geometrical properties of the underlying mesh.
