24 Class
25  Foam::fixedMeanOutletInletFvPatchField
26 
27 Description
28  This boundary condition extrapolates field to the patch using the near-cell
29  values and adjusts the distribution to match the specified, optionally
30  time-varying, mean value. This extrapolated field is applied as a
31  fixedValue for outflow faces but zeroGradient is applied to inflow faces.
32 
33  This boundary condition can be applied to pressure when inletOutlet is
34  applied to the velocity so that a zeroGradient condition is applied to the
35  pressure at inflow faces where the velocity is specified to avoid an
36  unphysical over-specification of the set of boundary conditions.
