i guess what you are looking for is the 'slip' condition

@ gregor,
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. |
