New Approx. Riemann Solver

January 27, 2000, 03:54

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 http://www.geocities.com/MotorCity/P...UBS/solver.doc (MS Word 6.0) http://www.geocities.com/MotorCity/P...PUBS/solver.ps (PostScript)

or from the Publications list at

http://www.geocities.com/MotorCity/Pit/9939/mypage.htm page

and enjoy it.

Well,

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.

Alexey.
