Artificial Viscosity Methods forModelling Shock Wave Propagation
The paper gives an overview of the artificial viscoity method widely used today to alow the simulation of problems containg shock waves. The development of the most common basic form of the viscosity term is summarised and its behaviour is illustrated through simulations of a 1D piston problem. Test problems that are commonly used to test different viscosity formulations are then discussed to further illustrate the method. Finally other shock viscosity forms such as edge and tensor viscosities are briefly discussed.
