Class
    Foam::inletOutletFaPatchField
 
Group
    grpOutletBoundaryConditions
 
Description
    This boundary condition provides a generic outflow condition, with
    specified inflow for the case of return flow.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | Flux field name         | no          | phi
        inletValue   | Inlet value for reverse flow | yes    |
        value        | initial field value          | optional |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            inletOutlet;
        phi             phi;
        inletValue      uniform 0;
        value           uniform 0;
    }
    \endverbatim
 
    The mode of operation is determined by the sign of the flux across the
    patch edges.
 
Note
    Sign conventions:
    - Positive flux (out of domain): apply zero-gradient condition
    - Negative flux (into domain): apply the "inletValue" fixed-value
