airfoil_ finite volumes method

I am working on 2D, incompressible, laminar viscous flow about an airfoil. I have used 'C grid generation' and finite volumes method with simpler algorithm and upwind second order schem. My code program written in fortran still diverge, perhaps because boundary conditions in calcul domain are not well imposed. Can you help me please to correct my code?

Re: airfoil_ finite volumes method

Thanks for y're response to help call. Please if y're ready i'll send you my code program with word file of mathematical model and other informations.

Re: airfoil_ finite volumes method

Mister dingxiwang, i h've sent you two messages to y're email, the first contains my code program with a data file for grid generation, and a word file explaining the problem. The second message contains a latest version of my code program. Thanks verry much for y're help

Re: airfoil_ finite volumes method

Please i've sent the message 'aerodyn3', with three files i've promised. If you h've received there please email me.

Re: airfoil_ finite volumes method

you probléme is the stretching of the gird

Re: airfoil_ finite volumes method

Salem Imad, Effectivelly i have a doubt about grid. I'm working with 'C grid', but when i increase the number of grids or the coefficients of stretching the code program dont work. Actually i'm using grid of (191x145) with stretching parameters 0.12 and 0.12, what may i use?

Friend Imad, thanks verry much and probably y're the unic one who understand my problem
