Hi all,

How do I get the residence times in Fluent? I'm not injecting any particls per se into the flow. I just want to know how long the fluid remains inisde my geometry and for how long they stay in each zone.

Thanks.

Hi Thomas,

I didn't find the residence time option in the COLORED BY menu.

Where can I find it?

Thanks.

Try step by step in particle tracking, I believe this could give you the residence time. Also see whether it is one way or two way coupling, it will give slight difference in result. Good luck.

Hi,

The particle tracking panel has the option for plotting/ writing to file the residence time values, but somehow I'm unable to activate the DISPLAY or WRITE buttons. It's always gray (inactive), no matter what I tried. How do I activate this?

As I said before, I do not have any injected particles in my flow stream.

Thanks.

The Display button of the Particle Tracks window will not work until you have selected a Injection in the "Release from Injections" - box( which is only possible if you have configured at least one injection. And you need some Iterations as well to see anithing) Hope, this helps a little,

Alex
