Description
This velocity inlet/outlet boundary condition is applied to pressure
boundaries where the pressure is specified. A zero-gradient condition is
applied for outflow (as defined by the flux); for inflow, the velocity is
obtained from the patch-face normal component of the internal-cell value and
the tangential patch velocity can be optionally specified.
obtained from the patch-face normal component of the internal-cell value.
The tangential patch velocity can be optionally specified.
