Hi everyone

I have a turbine model, created in GAMBIT, which I have imported into FLUENT where it is taking absolutely ages to iterate - we're talking 10 seconds between each iteration here! Where is my first port of call in terms of speeding it up?

Let me know what you think

David

how many cells in your mesh and what is your hardware conficuration (serial/cluser) how many RAM memory?

When I import the case file into FLUENT it tells me there are 2066572 interior faces and 1037553 mixed cells.

There is 48.8GB of free space in my C Drive - what do you mean by serial/cluster?

Cheers

Dave

ok you have about 1million cells. are you running fluent on one CPU or more than one (cluster)? if you are running it with one CPU (serial), then you should have at least 2GB Ram (virtual memory). But as fluent didn't gave you an error message regarding memory, it's supposed to be "ok" Try to reduce your mesh size (if you have full tetra mesh, switch on tet/hexcore... the amount of cells should decrease, as your domain could essentially be filled with hexa-) or spend more time on your mesh with sub-dividing it into volumes which can be meshed with hex-
