Hi,

As part of my master's thesis I'm trying to understand the implementation of the PISO algorithm in OpenFOAM. A crucial step in the PISO loop is the call to the H-operator, i.e. UEqn.H(). I understand what this operator is doing, but I can't seem to figure out whether it changes the matrix coefficients. I would assume it shouldn't, but perhaps you could shed some light on this.
