3.4.8 Substructure library utilities

Product: Abaqus/Standard  

Element tested

S4R5


Features tested

Utilities that copy a substructure definition from one library or substructure identifier to another, delete a substructure from a library, and summarize information about the substructures stored in a library are tested. Substructure regeneration is tested in conjunction with these utilities.

Problem description

The hemispherical shell model used in Substructure rotation, mirroring, transformation, and constraints, Section 3.4.1, is used to test the substructure utilities. 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 utility that provides a summary of information about the substructures is used to monitor the different libraries that are created.

You can combine the results of substructure analyses using the abaqus substructurecombine execution procedure. For more information, see Combining output from substructures, Section 3.2.24 of the Abaqus Analysis User's Guide.

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.
