Hi,

I am solving a 2D convection diffusion equation and also navier stokes using Finite Volume method. I would like to know whether any source codes are available for them. I saw some source codes like Open foam, overture, NaSt3DGP etc from the CFD online links. I would like to know out of all these source codes or others which one should I use (that is reasonably efficient, easy to comprehend and takes reasonably less computational time) to solve my problem.

Kindly help in this regard.

Thanks in Advance.

hi, I suggest you to refer the codes provided by Peric. See the appendix section of the book by the Ferziger and Peric for how to access the codes. It is written in fortran and really very simple and self-explanatory..

Thanks a lot for the reply. But i use C and not Fortran... so any C codes available

I will suggest the use of OpenFVM:

http://openfvm.sourceforge.net/

It is very easy to comprehend just as the codes of Peric. It is coded in C and not fortran. It can be easily compiled in both Windows and Linux. It also has a reference manual which describes the numerical methods used.

Note: For solving 2D convection/diffusion and navier-stokes, activate the calculation of u,v,p and T. Being T the solution of the convection/diffusion equation. This is done by changing the parameter (.par) file. For a quick start, look the tutorial in the reference manual.

Hi x flow,

Thanks a lot for the suggestions. I will download it and if I have any queries I need your help.

Thanks in advance.
