PISO vs. SIMPLEC
 
Hello,

I'm running a steady state incompressible turbulent flow problem and decided to try PISO instead of SIMPLEC and discovered that the oscillations in the residuals were reduced. Is there anybody that can support the conclusion that PISO might be more suitable for this kind of problem? (PISO was originally developed for transient compressible flow)

Regards

Andreas
