I have this mesh imported from GAMBIT, and profile file of velocity profile that I like to use imported.

Well, the catch is that I need to have the velocity profile going into the current mesh, but instead of the velocity profile going into the mesh, it's coming out of it. Say, I have the mesh oriented such that the positive X axis runs from left to right. The velocity profile I am trying to use supposed to act in the positive X direction but it is acting in the negative X direction.

How do I orient the direction of the profile opposite way?

Thank you.

just change signs of x-component velocity. You had to make a mistake. There cannot be wrong anything else

Hi

If you have read the "magnitude" of the velocity profile, specifying the profile "Normal to the Boundary" should take care of the (inward) direction with respect to the domain.
