Hi,
This post is closely related to: http://www.lbmethod.org/forum/read.php?3,2479,2508#msg-2508
I’m using the following setup:
i = inlet
o = outlet
X = WALL
XXXXXXXXXXXXXXXXXXXXXXXXXX
i ________________________o
i ________________________o
i ________________________o
i ________________________o
XXXXXXXXXXXXXXXXXXXXXXXXXX
I put a pressure boundary at inlet and outlet, the Zou/ He condition, as described in the above link.
I’m seeking a clarification, when I implement this type of method, I still have an increase in my x velocity at the outlet compared to the inlet, and some y direction velocity near the outlet both up and down.
Should the velocity not be uniform from inlet to outlet?
Does anyone else have this problem?
Thanks in advance for any advice.
