3.4.8 Substructure library utilities

Product: ABAQUS/Standard  

Element tested

S4R5   

Features tested

The substructure library utilities *SUBSTRUCTURE COPY, *SUBSTRUCTURE DELETE, and *SUBSTRUCTURE DIRECTORY are tested. Substructure regeneration is tested in conjunction with the above options.

Problem description

The hemispherical shell model used in Substructure rotation, mirroring, transformation, and constraints, Section 3.4.1, is used to test the *SUBSTRUCTURE COPY, *SUBSTRUCTURE DELETE, and *SUBSTRUCTURE DIRECTORY housekeeping options. The analysis is performed only at the third level of substructure; i.e., the analysis of half of a sphere. Library utilities are tested by moving and deleting the lower-level substructures from different libraries during the various stages of the generation. Regeneration of the substructure is also tested at the analysis stage. The *SUBSTRUCTURE DIRECTORY option is used to monitor the different libraries that are created.

Combining model and results data from more than one output database into a single output database, Section 9.15.4 of the ABAQUS Scripting User's Manual, illustrates how you can use a C++ program to combine the results from all the substructure analyses described here into a single output database.

Results and discussion

The results from the analysis match the results in the third-level analysis in Substructure rotation, mirroring, transformation, and constraints, Section 3.4.1.
