Preconditioning
 
Hi all,

is anybody studying on preconditioning techniques for Euler or NS equations? I'd like to hear about which methods you use and applications you work on..

greetings,

seckin

I have applied precondition method on my 2-D unstructured grids as Turkle said. Although it runs fine for Ma=0.01 or even lower, I find it not so good in high speed, and I haven't try the heat conduct problem!

Re: Preconditioning
 
thanks for the reply. I am working on a 2-D Euler code by Muradoglu whom has developed a new preconditioning method that works for various speeds. You can check that if you want. I am trying to apply Turkel's and Van Leer's methods at the moment.

regards,

Can you tell me how can I find the paper on the method you metioned!
