Velocity on boundary face is 0 with Parts Color enabled

Post process result shows 0 velocity at any given point, but my velocity inlet is about 98 m/s. However, if I close “Parts Color”, the velocity magnitude will no longer be 0. Why is this happening?

Hey Ian1128

Thanks for posting on the forum.

Could you share the link to your project here?


Does this link work?

Hi Ian1128,

Yes, it works.

According to me, everything is fine. Since you did not define boundary conditions for the side faces, it considers it to be a non-slip wall by default, so the velocity at that face will be 0 with Parts Color enabled.

With the cutting plane, you can see that your velocity contours are perfect.


Shenoy, thanks for the help!
