486 C cg2dpcOffDFac :: Averaging weight for preconditioner off-diagonal.
487 C Note. 20th May 1998
488 C I made a weird discovery! In the model paper we argue
489 C for the form of the preconditioner used here ( see
490 C A Finite-volume, Incompressible Navier-Stokes Model
491 C ...., Marshall et. al ). The algebra gives a simple
492 C 0.5 factor for the averaging of ac and aCw to get a
493 C symmettric pre-conditioner. By using a factor of 0.51
494 C i.e. scaling the off-diagonal terms in the
495 C preconditioner down slightly I managed to get the
496 C number of iterations for convergence in a test case to
497 C drop form 192 -> 134! Need to investigate this further!
498 C For now I have introduced a parameter cg2dpcOffDFac which
499 C defaults to 0.51 but can be set at runtime.
