Class
    Foam::uniformInletOutletFvPatchField
 
Description
    Variant of inletOutlet boundary condition with uniform inletValue.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | flux field name         | no          | phi
        uniformInletValue   | inlet value for reverse flow | yes    |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type                uniformInletOutlet;
        phi                 phi;
        uniformInletValue   0;
        value               uniform 0;
    }
    \endverbatim
 
    The mode of operation is determined by the sign of the flux across the
    patch faces.
 
    Note:
        Sign conventions:
      - positive flux (out of domain): apply zero-gradient condition
      - negative flux (into of domain): apply the user-specified fixed value
