How to add steger warming flux vector splitting in open foam
 
Hiii,
I am new to open foam and want to add steger warming flux vector splitting in it. Can any one tell me the process of adding? thanks in advance

could you describe better what do u want to implement?

You can modify rhoCentralFoam to add steger-warming fluxes. Thats what I did here

http://gfoam.svn.sourceforge.net/

though I have not added that particular flux.

Hiiii Praveen , thanks for your reply but i am currently working on openfoam 2.00 version. By seeing your link i am totally confused. Is it possible to send me some reference code (related to flux vector splitting) that u had done. It will really help me a lot. My mail id dushyantbajaj1984@gmail.com

Thanks & Regards
Dushyant

Hiiii nimasam
Thanks for showing your interest -- I had written a implicit code in c for the steger warming splitting . Now i want to add this scheme in OpenFoam as existing one like rhocentralfoam. So i need to know the process of doing it. I understood the oblique shock reflection problem solved using rhoCentralfoam but now i dnt know how to add my scheme and test this problem.

sorry i dont have no idea

All the code is available in the above link. I have not tried to compile it with 2.0.0

hi praveen
 
I excuted programmes given in the the above link, no problem with wmake but i am getteing the following errors when running with solver,
can you please tell me how to fix the following errors:
