Do you mean that without using Riemann-type upwind scheme, classical upwind scheme should capture shock speed well too? ( don't consider oscillation at this stage ) My puzzle now is that:...

TVD is more like an adjective, meaning non-oscillative. I am still a little confusing about Godunov and Riemann solver. I will look at Toro's...

Replies: 12 TVD？Riemann Solver? Shock Capture? Views: 3,580 Posted By nashiong TVD？Riemann Solver? Shock Capture? hi all: I am now studying shock capture scheme and I am really confusing about several conceptions. that's TVD scheme, limiters, Riemann solvers, Godunov type scheme. I want to get a...
