Hi everybody,

who is interested in approximate Rieman solvers!

Here is the description of the fastest solver which I use for unsteady simulations. I will be glad to hear some thoughts about it from you.

Download one of the following documents (MS Word 6.0) (PostScript)

or from the Publications list at page

and enjoy it.

Andrei Chernousov.

seems that nobody is interested in discussing Riemann solvers at CFD Online forum. That is discouraging...

Now there is a link to sample 1D code which uses this solver

Hello Andrew.

Your results are interesting. Try numerically solve the following Riemann 1-D problem for heat ratio 1.4: Left conditions: Density=1.4, Pressure=1, Velocity=-3 Right conditions: Density=1.4, Pressure=1, Velocity= 3 It would be fine if you get monotone solution for density profile with minimum value 0.014336 ! Please, inform me.
