pl. HELP: Convert TVD scheme from NV formulation
 
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

NV FORMULATION vs. NVSF FORMULATIOIN
 
Does anybody know, how better high resolution schemes in NVSF?

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?

Re: NV FORMULATION vs. NVSF FORMULATIOIN
 
In my experiqance the HLPA scheme is best for many incompresible flow calculations. 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.

Re: NV FORMULATION vs. NVSF FORMULATIOIN
 
I have send the articles to You.

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

Dear colleagues, please if anybody can, send me an article by Zhu J.

if I was in St.Petersburg, I would go to the library, but unfortunately I can not. I shall be very grateful.

If you give me your address by email or post it here, I will send the articles to you. I do not have electronic files for them.

Good luck

Dear Dr. Seok-Ki Choi, thank You very much
 
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
