Discuss about computation time of FLUENT

Kelly

Hello,

I am simulating flow using FLUENT in a small scale rectangualer pond (only 2m*4.6m*2m).The computations are really so demanding and time consuming.1 second is computed in about 2-3 hours. I wonder is it applicable to use FLUENT in a long time simualtion such as a storm which may last for several hours or even a day. If so it will last for at least half a year to finish computation.

My Problem:

- 3D unsteady simulation, - VOF (air-water), - k-epsilon, - PISO, - pressure: Body Force Weighted, - default under-relaxation factors - mesh size=0.1 m.

Can you present here some of your experiences? Thanks,

Kelly
