Robustness versus accuracy in shock-wave computations
Robustness versus accuracy in shock-wave computations
Despite constant progress in the development of upwind schemes, some failings still remain. Quirk recently reported (Quirk JJ. A contribution to the great Riemann solver debate. International Journal for Numerical Methods in Fluids 1994; 18: 555–574) that approximate Riemann solvers, which share the exact capture of contact discontinuities, generally suffer …
