In the fem part, I have used the new 'surface wrap' capability to determine the inner volume of an acoustic enclosure. Is there any way to apply modeling techniques like boolean add,, etc, to be able to manipulate and tweak this polygon body in the ideal or the master part ? I guess the first step would be to somehow 'include' this polygon body into the ideal or master part. I thought I saw sometime ago a paper on how to push fem polygon bodies upstream to ideal/master part but cannot locate it now. Thanks.
