No-slip B.C.
 

Dear All
Hello

I have simulated a simple channel.

At the bottom of the channel, I applied the No-Slip B.C.

As far as I know, at this boundary, the velocity is zero. But the vectors show that it is NOT.

How do you explain this?

Hello
In flow-3D, results have been presented in center of each cells. So, near the bottom, you have results (velocity ,etc.) in half of height cell.
