C Note. 20th May 1998 |
140 |
|
C I made a weird discovery! In the model paper we argue |
141 |
|
C for the form of the preconditioner used here ( see |
142 |
|
C A Finite-volume, Incompressible Navier-Stokes Model |
143 |
|
C ...., Marshall et. al ). The algebra gives a simple |
144 |
|
C 0.5 factor for the averaging of ac and aCw to get a |
145 |
|
C symmettric pre-conditioner. By using a factor of 0.51 |
146 |
|
C i.e. scaling the off-diagonal terms in the |
147 |
|
C preconditioner down slightly I managed to get the |
148 |
|
C number of iterations for convergence in a test case to |
149 |
|
C drop form 192 -> 134! Need to investigate this further! |
150 |

C For now I have introduced a parameter cg2dpcOffDFac which |
151 |

C defaults to 0.51 but can be set at runtime. |
