384 C Note. 20th May 1998
385 C I made a weird discovery! In the model paper we argue
386 C for the form of the preconditioner used here ( see
387 C A Finite-volume, Incompressible Navier-Stokes Model
388 C ...., Marshall et. al ). The algebra gives a simple
389 C 0.5 factor for the averaging of ac and aCw to get a
390 C symmettric pre-conditioner. By using a factor of 0.51
391 C i.e. scaling the off-diagonal terms in the
392 C preconditioner down slightly I managed to get the
393 C number of iterations for convergence in a test case to
394 C drop form 192 -> 134! Need to investigate this further!
