Subset Definition

21 22


  1. A subset is a non-homogeneous element assembly.
  2. A subset contains a set of parts and (or) a set of subsets. Subsets can be structured to generate a hierarchical model.
  3. The subset to which a part belongs is defined in the /PART option.
  4. The subsets belonging to one subset are defined with the /SUBSET option.
  5. 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.
  6. Subsets not referenced in any /SUBSET option list are children of the global model subset.
  7. 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.
  8. The number of levels in a hierarchical organization is not limited.
