List {special_type} <range>
Special entities include (element) blocks, sidesets and nodesets (representing boundary conditions). Like the list geometry and list mesh commands, if no range is specified then the number of entities of the given type is summarized. Otherwise, listing a special entity prints the mesh and geometry it contains.
(Some special entities are of interest mainly to developers and are not described here, e.g. whisker sheets, and whisker hexes.)
