Class
    Foam::emptyFvPatchField
 
Description
    This boundary condition provides an 'empty' condition for reduced
    dimensions cases, i.e. 1- and 2-D geometries.  Apply this condition to
    patches whose normal is aligned to geometric directions that do not
    constitute solution directions.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            empty;
    }
    \endverbatim
