Class
    Foam::outletInletFaPatchField
 
Group
    grpInletBoundaryConditions
 
Description
    This boundary condition provides a generic inflow condition, with
    specified outflow for the case of reverse flow.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | Flux field name         | no          | phi
        outletValue  | Outlet value for reverse flow | yes   |
        value        | initial field value     | optional |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            outletInlet;
        phi             phi;
        outletValue     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 the "outletValue" fixed-value
    - Negative flux (into domain): apply zero-gradient condition
