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