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. |
