Class
    Foam::matchedFlowRateOutletVelocityFvPatchVectorField
 
Group
    grpOutletBoundaryConditions
 
Description
    Velocity outlet boundary condition which corrects the extrapolated velocity
    to match the flow rate of the specified corresponding inlet patch.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        inletPatch   | Corresponding inlet patch name | yes  |
        volumetric   | Set volumetric or mass flow-rate | no | false
        rho          | density field name      | no          | rho
    \endtable
 
    Example of the boundary condition specification for a volumetric flow rate:
    \verbatim
    <patchName>
    {
        type                matchedFlowRateOutletVelocity;
        inletPatch          inlet;
        value               uniform (0 0 0);
    }
    \endverbatim
