Dear OpenFOAM User's,

I would like to know if anybody know what is the major meaning of this term into the PISO loop in pisoFOAM
Here is the U solution of the matrix
U = rUA*UEqn.H();
This step is to calculate the phi the first term in the right hand is like the phi = U & A, is the interpolation the U field scalar product the area.
phi = (fvc::interpolate(U) & mesh.Sf())
+ fvc::ddtPhiCorr(rUA, U, phi);
But I don't understand very well about the second term???.

I'll be waiting your advise. Thanks in advance

Respectfully
Javier
