 January 27, 2000, 03:54 New Approx. Riemann Solver #1 Andrei Chernousov Guest   Posts: n/a 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. Andrei Chernousov.

 February 15, 2000, 05:31 Re: New Approx. Riemann Solver #4 Alexey Guest   Posts: n/a 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.
