Shock detection and capturing methods for high order Discontinuous-Galerkin Finite Element Methods
High-order Discontinuous Galerkin (DG) methods have shown a lot of promise in being able to provide high accuracy and efficiency as well as the flexibility to handle complex unstructured grids. However in order to solve compressible flow problems effectively, we need to be able to detect discontinuities/shocks in the flow and capture them effectively such that the solution accuracy is not affec...
متن کاملSub-Cell Shock Capturing for Discontinuous Galerkin Methods
A shock capturing strategy for higher order Discontinuous Galerkin approximations of scalar conservation laws is presented. We show how the original explicit artificial viscosity methods proposed over fifty years ago for finite volume methods, can be used very effectively in the context of high order approximations. Rather than relying on the dissipation inherent in Discontinuous Galerkin appro...
متن کاملHigh-Order Discontinuous Galerkin Methods for CFD
In recent years it has become clear that the current computational methods for scientific and engineering phenomena are inadequate for many challenging problems. Examples of these problems are wave propagation, turbulent fluid flow, as well as problems involving nonlinear interactions and multiple scales. This has resulted in a significant interest in so-called high-order accurate methods, whic...
متن کاملShock Capturing for High-Order Discontinuous Galerkin Simulation of Transient Flow Problems
We present some recent results for shock capturing using high-order discontinuous Galerkin schemes on fully unstructured meshes. We study the application of sensor-based artificial viscosity to problem with moving shocks, time-stepped using high-order accurate implicit schemes with Jacobian-based Newton-Krylov solvers. We demonstrate that the sensors can be coupled weakly without losing robustn...
متن کاملShock Capturing with Discontinuous Galerkin Method
Shock capturing has been a challenge for computational fluid dynamicists over the years. This article deals with discontinuous Galerkin method to solve the hyperbolic equations in which solutions may develop discontinuities in finite time. The high order discontinuous Galerkin method combining the basis of finite volume and finite element methods has shown a lot of attractive features for a wid...
