 February 18, 2005, 05:38 Velocity inlet problem #1 KKLAU Guest   Posts: n/a Sponsored Links To fluent experts, If i set the velocity inlet value to 0 m/s in xy direction, does it same with the wall boundary condition? I tried to both cases and found that they are different? Can you anyone tell me why ??? Thank you. KKLAU

Try the segregated! it should work. What are you trying to simulate? Pay a lot of attention with this trick... Luca

As is my understanding it sets the x, z (and if 3d z) velocity to zero. Are you setting all two (or three in 3d) components to zero? If so, what values of flow are at the "wall/velocity inlet" when you plot contours of x, y and z velocity, and how do they differ from just using a regular wall?
