Description: A new optional argument, readInternalSets, has been added to the openOdb method in the Abaqus Scripting Interface. By default, readInternalSets is False, and scripts can access only those sets that you have created and saved. Set readInternalSets to True to access internal sets created by Abaqus. A new member, isInternal, is also available for sets so that you can test whether a set is an internal set or a regular set.
