Churchfield Join Date: Nov 2009 Location: Boulder, Colorado, USA Posts: 49 Rep Power: 18	Can someone please point me toward a reference that describes the diagonal incomplete Cholesky preconditioning used in OpenFOAM? It would be much appreciated. What I don't understand is the "diagonal" part. What exactly does that mean? Thank you, Matt
