Is there a software that couples p and U?
Hi all,
I am facing an interesting problem and I can't get convergence. I think that the problem is in the numerical resolution. I would need a scheme that couples p and U. Is there such a scheme in OF? Thanks a lot, Samuele 
Hi
Do you really mean scheme? or coupling algorithm? 
Let's say coupling algorithm!

Hi
I am confused what really you want but there is SIMPLE, PISO and ... algorithms in OF. 
Yes,
I know. But AFAIK, both simple and piso solved the P field first and then the U field, is that correct. I know that in fluent there is a solver which solved the U and P field together at each iteration. 
Hi
Now I understand you. Is your problem compressible or weakly compressible? 
Ok.
Sorry, I didn't explain the problem well. Anyway, my problem is compressible 
Oh!
As I know unfortunately there is not such solver in OF. 
And do you have any suggestion for a weakcompressible problem?

Hi
Not specific offer just using a compressible equation of state and setting Match number low to be weakly compressible. 
OpenFOAM extend offers a blockcoupled solution strategy. Unfortunately, that's all I know about it ;) Google blockcoupledmatrix...

Thanks.
I'll google it as soon as possible. Samuele
