Article by Leonard  Normalized Variable technique
Hi All.
I am writing about approximation schemes. I have short description of NV (from other sources) but I have not the original work by '''B.P.Leonard''' Simple highaccuracy resolution program for convective modelling of discontinuities. International J. Numerical Methods Fluids, 8:12911318, 1988 If I'll be glad if anyone can help. Unfortunatly I am out of the libraries. Michail 
Re: Article by Leonard  Normalized Variable techn
I'll be at Chalmers tomorrow Michail. If I get some spare time I'll try to drop by their library to get you some of those papers you are missing. Could you post a list of papers that you would like to have?

Re: Article by Leonard  Normalized Variable techn
if you meet (by chance) prof. lars davidson, say my thanks for his course notes, i learnt a lot from his notes specially LES. :)

Re: Article by Leonard  Normalized Variable techn
I know Lars well, his room was a few meters away from mine when I was at Chalmers. I'll send him your thanks.

Jonas  Thank You Very much
Dear Jonas, thanks a lot, I am very grateful for Your offer.
But I still have a lot to do even without additional literature, besides I've found something in the Internet. And to be honest I don't want to take Your time, bother You and add my personal troubles and problems to Your own. I suppose when we open CFDWiki defenitely appear people who will want and decide to make his contribution. At least I hope that we have enough time  some 10 or 20 years :)) 
Re: Jonas  Thank You Very much
No problem, if I have some spare time I'll try to copy some papers for you. I have a 6hour meeting there on monday so a break is always nice. Post the list of papers that you want and if I can't get the papers for your perhaps someone else has the opportunity sometime.

Re: Jonas  Thank You Very much
ok, thanks a lot, just a few minutes

Dear Jonas  Thank You Very much  Any of them
Main problem with this schemes  they are not often in use, it was some kind of discovery for me  I've never heard of them.

Re: Dear Jonas  Thank You Very much  Any of them
I copied at least one long paper for you. The older papers (earlier than 1994) was in the library magazine and they had closed for the day when I was there. Anyway, email me your address and I'll send you the 1995 Nirvana article.

Re: Dear Jonas  Thank You Very much  Any of them
Michail,
if you find any of the topic you have mentioned in AIAA papers, you can write to vinod on this email: dhimanvinod@gmail.com he will mail you the paper if it is available in pdf form. He is a nice guy, i have asked him for so many papers and he has not disappointed me yet. 
Re: Dear Jonas  Thank You Very much  Any of them
Thank You Arjun, but:
1) I don't know him 2) I try to don't bother people until theyselves agreeds to help. Of course, sometimes I sent letters with begging to help, but I think it's not the case, where such method could be applied. I placed a page with a list of what we need, perhaps some people will answer to our petition. http://www.cfdonline.com/Wiki/index...d:_Please_help 
Re: Dear Jonas  Thank You Very much  Any of them
well i understand what u r saying, but sometimes u know there are people who wish to help others, but u see they can not help until some one asks them to help(how they will know u need help). you got my point, lets assume that vinod wants to help you, but how will he know that u need somehelp. so drop a line to him. no need to beg, he is good guy. same thing apply to me, i wish to help lot of guys, but can not really do until someone asks me. think again.

Re: Dear Jonas  Thank You Very much  Any of them
I suppose, we have not anything to be in hurry.
Therefore I hope, that when someone good guy have a glance on the page where I wrote, what we need  (if he will be really "good guy")  I am sure  he will answer. I think that trouble and annoy people without serious reason  is not the goodlooking thing. So I shall try not to do this, and shall try to avoid such situations as much as possible.

Hi Sir,
I am a student .My major is CFD.Your Email displayed in the web,so I can connect with you now. Does you have an electronic or hard copy of this paper: Leonard, B. P. 1979," A stable and accurate convective modelling procedure based on quadratic upstream interpolation". Comp. Meth. Appl. Mech. & Engg. 19, p5998. I look forward to your early reply.
