Simple high-resolution upwind scheme
WebbUpwind Schemes Turbulence Equations Introduction Convective schemes are used in the FVM discretization of convective fluxes through the faces of the dual-grid control volumes. They are selected via option CONV_NUM_METHOD_FLOW and fall under the two broad categories of central and upwind. WebbUsing high-resolution relaxation schemes to approximate the solutions of second-order traffic flow models was presented in [29,32]. The relaxation scheme is based on constructing a linear system with stiff relaxation source term (known as the relaxation system) to replace the given conservation law. However, the 4

Book Description A comparative study of five upwind schemes was performed to evaluate their ability accurately model the convective fluxes of the Euler equations for problems containing complex shock structure. High-resolution schemes are used in the numerical solution of partial differential equations where high accuracy is required in the presence of shocks or discontinuities. They have the following properties: • Second- or higher-order spatial accuracy is obtained in smooth parts of the solution.
