| 433 |
C Note. 20th May 1998 |
| 434 |
C I made a weird discovery! In the model paper we argue |
| 435 |
C for the form of the preconditioner used here ( see |
| 436 |
C A Finite-volume, Incompressible Navier-Stokes Model |
| 437 |
C ...., Marshall et. al ). The algebra gives a simple |
| 438 |
C 0.5 factor for the averaging of ac and aCw to get a |
| 439 |
C symmettric pre-conditioner. By using a factor of 0.51 |
| 440 |
C i.e. scaling the off-diagonal terms in the |
| 441 |
C preconditioner down slightly I managed to get the |
| 442 |
C number of iterations for convergence in a test case to |
| 443 |
C drop form 192 -> 134! Need to investigate this further! |
