            Comments
- A subset is a non-homogeneous element assembly.
 - A subset contains a set of parts and (or) a set of subsets. Subsets can be structured to generate a hierarchical model.
 - The subset to which a part belongs is defined in the /PART option.
 - The subsets belonging to one subset are defined with the /SUBSET option.
 - Each subset ID referenced by /PART option or by /SUBSET option has to be defined with a /SUBSET option. The same subset_ID can only be referenced once for all /SUBSET options.
 - Subsets not referenced in any /SUBSET option list are children of the global model subset.
 - The main difference between a subset and an element group (/GRSHEL, /GRBRIC, ...) is that a subset hierarchy defines a complete non-redundant model organization. Elements groups only cover one part of the model, and some elements can belong to several groups.
 - The number of levels in a hierarchical
                organization is not limited.
