Class
    Foam::translatingWallVelocityFvPatchVectorField

Group
    grpWallBoundaryConditions grpGenericBoundaryConditions

Description
    This boundary condition provides a velocity condition for translational
    motion on walls.

Usage
    \table
        Property     | Description             | Required    | Default value
        U            | translational velocity  | yes         |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            translatingWallVelocity;
        U               (100 0 0);
    }
    \endverbatim

    The \c U entry is a Function1 of time, see Foam::Function1Types.
