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

| Example of the boundary condition specification: | |
| \verbatim | |
| <patchName> | |
| { | |
| type fixedMeanOutletInlet; | |
| meanValue 1.0; | |
| } | |
