Class
    Foam::emptyFvsPatchField

Description
    This boundary condition provides an 'empty' condition for reduced
    dimensions cases.

    The "value" entry is NO_READ, NO_WRITE.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type    empty;
    }
    \endverbatim
