Hi,

I need to modify a no slip wall boundary condition:

Wall :
Fluid normal (z-) velocity component = 0
No slip :
Fluid tangential (x and y) velocity = wall velocity

Custom part :
Fluid velocity in the z+ direction = 0
***Adding this part in a boundary condition is what I’m looking for***

Do someone know how to create a custom boundary condition on CFX?
