WebThis spatial DG discretization avoids the use of penalty parameters (called penalty-free DG method) in the numerical flux on interior cell interfaces. It also inherits most of the advantages of the usual DG methods (see e.g., [8, 17, 18]), such as high order accuracy, flexibility in hp-adaptation, capacity to handle domains with complex geometry.

WebNov 21, 2015 · The discontinuous Galerkin (DG) method is a class of finite element methods using completely discontinuous basis functions to approximate partial differential equations (PDEs). It was first designed for steady-state scalar linear hyperbolic equations [ 15] in 1973. Early analysis of the method was performed in [ 11, 13 ]. Discontinuous Galerkin methods were first proposed and analyzed in the early 1970s as a technique to numerically solve partial differential equations.
