Comments
- The format is the same as the corresponding options /SURF/type/surf_ID.
- Input format for
BOX:
- The external faces are built from all solids (the inner faces are not considered).
- The segments built from 3-node and 4-node shells are still selected the same way as with /SURF/type/surf_ID and segments from inside of volumic parts (inner segments) will also be excluded.
- If type is
BOX, all segments supported by solids, shells and 3-node
shells with all nodes inside the box or on its external surface are selected
(segments lying on solid elements are not considered).
- If type is BOX2, all segments with at least one node inside the box or on its surface are selected.
