<B>Description:</B>
    This checker searches for all sublevel solid bodies in which the volume of the solid
    is less than the specified tolerance.
    Solids that fall short of a particular dimension in two directions in space should be
    avoided. Depending on the interface and the system internal parameter for the degree of
    accuracy, these elements can cause problems or be lost during the exchange of data. Often
    these elements may also occur unintentionally during the modeling process (i.e., intersection
    of two solids that only slightly penetrate each other) and cannot be produced.
    Recommendation: This error source can be eliminated through displacing or enlarging the
    affected elements. If appropriate, remove tiny elements entirely, or eliminate them by
    enlarging the neighboring elements and then deleting the tiny elements.
