Utility routines GETPARTINFO and VGETPARTINFO can be called from any ABAQUS/Standard or ABAQUS/Explicit user subroutine, respectively, to retrieve the part instance name and original node or element number corresponding to an internal node or element number. Utility routines GETINTERNAL and VGETINTERNAL can be called from any ABAQUS/Standard or ABAQUS/Explicit user subroutine, respectively, to retrieve the internal node or element number corresponding to a part instance name and original node or element number. The part file (jobname.prt) must be available. The expense of calling these routines is not trivial, so minimal use of them is recommended.
