This command creates integer attributes that contain the node and/or element number. This is useful if later operations delete nodes or elements causing renumbering, these attributes will contain the original node or element number.
cmo/set_id /mo_name/ both node element /[attribute_name1]/[attribute_name2]
mo_name is the name of the mesh object.
both or node or element indicate which attributes to create, node numbers, element numbers, or both. If no attribute name is given on the command line, the default attribute names id_node or id_elem will be used.

cmo/set_id/cmo1/both
cmo/set_id/cmo1/node/id_node2
cmo/set_id/cmo1/element/id_elem2
These set_id commands will add node and element attributes to the mesh object cmo1. Node and element id numbers will be written to default node attribute names id_node id_elem and another set of id numbers will be written to user attributes with names id_node2 id_elem2

This example copies node id numbers into node attribute id_node1 and element id numbers into element attribute id_elem1. A set of points are selected within a box shaped geometry and then deleted. The rmpoint/compress will remove the nodes tagged for removal and reorder the mesh nodes and element to their new size. The original node and element id numbers are preserved in the added attributes.
