How To Set Velocity Outlet Boundary Conditions?


How should I set velocity outlet boundary conditions?


If you use Fixed value, you need to define velocity with respect to the coordinate system. This means, based on the flow direction, assign U_x, U_y, U_z and set (+) or () whether the direction is in positive or negative axis.

If you use flow rate, you need to define either

  • Mass flow rate, or
  • Volume flow rate

In this case, you need to define flow rate as negative to ensure that flow leaves the domain.
