specifying U components as boundary condition
I want to specify different boundary conditions for Ux, Uy and Uz :confused:
fixed value : 0 for Uy and Uz
zeroGradient : Ux
How I can do that? Can anyone please help! (sorry,I could not find ans. for the older posts)
i guess what you are looking for is the 'slip' condition
The slip boundary condition does the opposite way.
For a patch parallel to yz -plane,
Instead of making Uy,Uz = 0 it makes Ux=0
Instead of zeroGradient at Ux it makes Uy,Uz zeroGradient.
After going through, the user guide what I understood is pressureInletVelcoity
looks similar to what I want. But I don't know if it works when total Pressure is specified.
I just spent some time with directionMixed BC and thats what I want.
