Class
    Foam::movingWallVelocityFvPatchVectorField

Group
    grpWallBoundaryConditions

Description
    This boundary condition provides a velocity condition for cases with
    moving walls.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            movingWallVelocity;
        value           uniform (0 0 0);    // Initial value
    }
    \endverbatim
