PISO Reference
 

Hi Foamers,

I have just read The description of PISO and SIMPLE from the nVersteeg e Malaskera book. When I compared with the algorithm implemented in icoFoam, I noted a lot of differences between the algorithms described in the book and the implementation. Is there other good reference where I can get more details about the implementation, in particular for flows different from those simulated by icoFoam.

Thanks in advance,

António Martins

Hi António,

This paper, by Fabian Peng Kärrholm, describes the PISO loop used in OpenFOAM solvers: http://www.tfd.chalmers.se/~hani/kur...7/rhiechow.pdf

I think there's also some info in the wiki.
