442    C     Note. 20th May 1998
443    C           I made a weird discovery! In the model paper we argue
444    C           for the form of the preconditioner used here ( see
445    C           A Finite-volume, Incompressible Navier-Stokes Model
446    C           ...., Marshall et. al ). The algebra gives a simple
447    C           0.5 factor for the averaging of ac and aCw to get a
448    C           symmettric pre-conditioner. By using a factor of 0.51
449    C           i.e. scaling the off-diagonal terms in the
450    C           preconditioner down slightly I managed to get the
451    C           number of iterations for convergence in a test case to
452    C           drop form 192 -> 134! Need to investigate this further!
453    C           For now I have introduced a parameter cg2dpcOffDFac which
