352    C     Note. 20th May 1998
353    C           I made a weird discovery! In the model paper we argue
354    C           for the form of the preconditioner used here ( see
355    C           A Finite-volume, Incompressible Navier-Stokes Model
356    C           ...., Marshall et. al ). The algebra gives a simple
357    C           0.5 factor for the averaging of ac and aCw to get a
358    C           symmettric pre-conditioner. By using a factor of 0.51
359    C           i.e. scaling the off-diagonal terms in the
360    C           preconditioner down slightly I managed to get the
361    C           number of iterations for convergence in a test case to
362    C           drop form 192 -> 134! Need to investigate this further!
363    C           For now I have introduced a parameter cg2dpcOffDFac which
