342     C Note. 20th May 1998
343     C I made a weird discovery! In the model paper we argue
344     C for the form of the preconditioner used here ( see
345     C A Finite-volume, Incompressible Navier-Stokes Model
346     C ...., Marshall et. al ). The algebra gives a simple
347     C 0.5 factor for the averaging of ac and aCw to get a
348     C symmettric pre-conditioner. By using a factor of 0.51
349     C i.e. scaling the off-diagonal terms in the
350     C preconditioner down slightly I managed to get the
351     C number of iterations for convergence in a test case to
352     C drop form 192 -> 134! Need to investigate this further!
