546     C Note. 20th May 1998
547     C I made a weird discovery! In the model paper we argue
548     C for the form of the preconditioner used here ( see
549     C A Finite-volume, Incompressible Navier-Stokes Model
550     C ...., Marshall et. al ). The algebra gives a simple
551     C 0.5 factor for the averaging of ac and aCw to get a
552     C symmettric pre-conditioner. By using a factor of 0.51
553     C i.e. scaling the off-diagonal terms in the
554     C preconditioner down slightly I managed to get the
555     C number of iterations for convergence in a test case to
556     C drop form 192 -> 134! Need to investigate this further!
557     C For now I have introduced a parameter cg2dpcOffDFac which
