Class
    Foam::movingWallVelocityFvPatchVectorField
 
Group
    grpWallBoundaryConditions
 
Description
    This boundary condition provides a velocity condition for cases with
    moving walls.  In addition, it should also be applied to 'moving' walls
    for moving reference frame (MRF) calculations.
 
 
    \heading Patch usage
 
    \table
        Property     | Description             | Required    | Default value
        U            | velociy field name      | no          | U
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            movingWallVelocity;
        U               U;
        value           uniform (0 0 0);    // initial value
    }
    \endverbatim
