252 C cg2dpcOffDFac - Averaging weight for preconditioner off-diagonal.
253 C Note. 20th May 1998
254 C I made a weird discovery! In the model paper we argue
255 C for the form of the preconditioner used here ( see
256 C A Finite-volume, Incompressible Navier-Stokes Model
257 C ...., Marshall et. al ). The algebra gives a simple
258 C 0.5 factor for the averaging of ac and aCw to get a
259 C symmettric pre-conditioner. By using a factor of 0.51
260 C i.e. scaling the off-diagonal terms in the
261 C preconditioner down slightly I managed to get the
262 C number of iterations for convergence in a test case to
263 C drop form 192 -> 134! Need to investigate this further!
