Class
    Foam::pressureInletOutletParSlipVelocityFvPatchVectorField
 
Group
    grpInletBoundaryConditions grpOutletBoundaryConditions
 
Description
    This velocity inlet/outlet boundary condition for pressure boundary where
    the pressure is specified.  A zero-gradient is applied for outflow (as
    defined by the flux); for inflow, the velocity is obtained from the flux
    with the specified inlet direction.
 
    A slip condition is applied tangential to the patch.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | flux field name         | no          | phi
        rho          | density field name      | no          | rho
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            pressureInletOutletParSlipVelocity;
        value           uniform 0;
    }
    \endverbatim
 
Note
    Sign conventions:
    - positive flux (out of domain): apply zero-gradient condition
    - negative flux (into of domain): derive from the flux with specified
      direction
