Fluent 6.2 slower than 6.122?
 

Hi guys,

I recently upgraded to 6.2 from 6.122. If I run exactly the same case with the same settings in 6.2 - it estimates 14hours for 3000 iterations....while 6.1.22 estimates 10 hours !

Thats 4 hours difference ! Any comments, suggestions? Why is 6.2 running slower?

Is it *actually* running slower, is is it just a bad estimate?

After checking again, I think the estimates are off in the beginnning. I can start the same case several times and the estimates will be way out.

I do not know what is causing this, but if it does it, all I do is restart and rerun and then it seems to be better.

If you're using Windoze, you should place as little confidence as you can on the time for iteration statistics.

Definetly. With the Eulerian model, which is the model I use more often, it's slower.
