Class
    Foam::pressureDirectedInletVelocityFvPatchVectorField
 
Group
    grpInletBoundaryConditions
 
Description
    This velocity inlet boundary condition is applied to patches where the
    pressure is specified.  The inflow velocity is obtained from the flux with
    the specified inlet direction" direction.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | flux field name         | no          | phi
        rho          | density field name      | no          | rho
        inletDirection | inlet direction per patch face | yes |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            pressureDirectedInletVelocity;
        phi             phi;
        rho             rho;
        inletDirection  uniform (1 0 0);
        value           uniform 0;
    }
    \endverbatim
 
Note
    If reverse flow is possible or expected use the
    pressureDirectedInletOutletVelocityFvPatchVectorField condition instead.
