 July 21, 2005, 12:38 pl. HELP: Convert TVD scheme from NV formulation #1 Michail Guest   Posts: n/a Dear friends I work on implementation of high-order and TVD schemes for convective terms. I found some literature, but have faced with a problem: In the most issues was used formulation of schemes in normalized variables. For program implementation I need a formulation in usual variables with distinguishing of first-order upwind part and other part, which will go to the source term. Any suggestions will be highly appreciated Thanks in advance Mike

I used QUICK and HLPA and on non-orthogonal non-uniformed grids and rather succesfully. I found an article with NVSF formulation of high oder schemes and thinking now, will it worth to use NVSF?

The SMART scheme shows an oscillation problem in a certain problem. Can you show me the article you have read? You know that the NVF by Gaskel and Lau is applicable to the scheme lower than 3-order accuracy.

I also find HLPA scheme the best for incompressible flow caculations and fond of it. But I am going to implement others schemes and try it on Smith-Hutton task. If You have good descrition of HLPA, won't it be difficult for You to send it to me? (I have, but it rather restricted). Best wishes Mike

I shall be very grateful. --------------------------------------------------------------------------- Zhu J.

(HLPA scheme) #9 Michail Guest   Posts: n/a Dear Halim, thanks a lot for Your help here is my Email (use it) michailkirichkov@yahoo.com.au also there I found some reviews: www.tfd.chalmers.se/~lada/ postscript_files/numer_methods_zhou.pdf http://citeseer.ist.psu.edu/zijlema95higher.html (download PS.gz) www.simuserve.com/support/docs/numerics/schemes.doc again thank You very much

 July 30, 2005, 12:09 Dear Dr. Seok-Ki Choi, thank You very much #10 Michail Guest   Posts: n/a Dear Dr. Seok-Ki Choi I have got the papers, thank You very much. I can not express my gratitude to You for Your help. You are very generous, that DHL post I guess, was very expensive. Excuse me for my offer (about beer), it was rather impolite from my side, but I did not know that You are Doctor of Science. Again Thanks a lot for You help. Respectfully Yours Michail
