Class
    Foam::fv::patchMeanVelocityForce
 
Description
    Applies the force over the specified patch to maintain
    the specified mean velocity for incompressible flows.
 
    Sources applied to:
    \verbatim
      U         | Velocity                                   [m/s]
    \endverbatim
 
    Required fields:
    \verbatim
      U         | Velocity                                   [m/s]
    \endverbatim
 
Usage
    Minimal example by using \c constant/fvOptions:
    \verbatim
    patchMeanVelocityForce1
    {
        // Mandatory entries (unmodifiable)
        type                 patchMeanVelocityForce;
        patch                <patchName>;
 
        // Mandatory/Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                       | Type   | Reqd  | Dflt
      type      | Type name: patchMeanVelocityForce | word   | yes   | -
      patch     | Name of operand patch             | word   | yes   | -
    \endtable
