Dear all, I noticed this today. I was doing a simulation of an infinitely long cylinder (2D) in crossflow from a tutorial.

What I noticed, is that, when moving the mouse in the FLUENT window, the solution time went down from 1:30:00 to about 00:05:00 and the solution did work out correctly as well as very short in time.

Can anyone explain this or even prove it? I know it sounds ridiculous but it's true and I've been flabbergasted with it.

I've even showed it to a friend of mine who has no explanation.

Thanks all

So do you agree with me that this is true?

Well there was a time when I used to think scrolling my download manager scrollbar accelerated the download

But probably all these are happy coincidences with different reasons? Is this phenomenon repetitive, for the same model and all other models you work on?

Hi, yes I noticed it on other simulations such as an aerofoil. For the cylinder that I was testing, it definitely solved in shorter time and the result was also the same.

I was testing the tutorials found online from Cornell university

This is a well known bug, at least for the Ansys guys...
This can happen, when you start Fluent in workbench with multi-core. (At least in version 14.0). Just don't use workbench and you will be fine...
