Class
    Foam::pressureInletUniformVelocityFvPatchVectorField

Group
    grpInletBoundaryConditions

Description
    This velocity inlet boundary condition is applied to patches where the
    pressure is specified.  The uniform inflow velocity is obtained by
    averaging the flux over the patch, and then applying it in the direction
    normal to the patch faces.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            pressureInletUniformVelocity;
        value           uniform 0;
    }
    \endverbatim
