I am using a turbulence model for which I have to know the mean velocity (time average). I am currently using the "Umean" option in FOAM. Could anyone please tell me whether "Umean" is a time average or not, and if so, in what time interval interval. I just want to know how FOAM finds the average velocity (Umean) before I use Umean.

Thanks,
