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 whole picture at first.
My understanding is TVD is another saying for limiter, and confine the interpolation to prevent from upshoot and downshoot, Riemann solver evaluates flux at cell face, is somekind of analytical solution. So we first use TVD to evaluate value, then use this value for Riemann solver for flux. I don't know what is Godunov type scheme.
I would rather appreciate for your help
