Has anyone tried a delta form of pressure equation pressurecorrection equation with OpenFOAM

I'll appreciate if someoen can tell me what it takes to solve (implement) pressure-correction equation in OpenFOAM.

Sung-Eun,

One thing that you should be careful about, when you go changing the interior PISO loop is that the solution to the pressure equation is sensitive to the value of p as you declare pEqn, as the pre-existing p field is used for the explicit treatment of the non-orthoganality correction.

Dave, how are you doing?

Yes, I've once read it. Nicely done! The reason I'm interested in the delta-form of presure equation is its potential benefits for some situations that I know from my experience with similar FV codes. I'm sorry that my question was probably too broad, which I think was why there has been little reponse.
