This book covers both theory and computation as it focuses on three primal DG methods--the symmetric interior penalty Galerkin, incomplete interior penalty Galerkin, and nonsymmetric ... WebJan 9, 2024 · Discontinuous Galerkin (DG) methods are a class of finite element methods that use discontinuous basis functions. This particular feature enables the use of non-conforming meshes and facilitates the use of meshes with a non-uniform degree of approximation.
