inletOutlet for velocity but seems go in sometimes
 
1 Attachment(s)
Hi, everyone!

I have a problem. In my LES simulation, I implement inletOutlet for velocity at a boundary normal to z direction. So, uz is supposed to be > or = 0 at the boundary.

Quote:
type inletOutlet;
inletValue uniform (0 0 0);
value uniform (0 0 0);
What's confusing is, at the boundary, uz is < 0 (means the flow goes inside) sometimes.

I would be very happy if anyone leave some comments on this.
