Products: ABAQUS/Standard ABAQUS/Explicit ABAQUS/CAE
Benefits: Enhancements to the submodeling procedure in ABAQUS result in faster processing of the submodel driven nodes and easier handling of sequentially coupled thermal-stress analysis.
Description: A new search algorithm has been implemented for processing the submodel driven nodes. The analysis preprocessing time for submodeling analyses has been significantly reduced, especially for cases with large numbers of driven nodes.
You no longer need to include the results file or output database file extension for the global model. If the extension is omitted and both results and output database files exist, the results file from the global model is used for the submodel analysis.
Submodeling thermal-stress analyses can now be carried out in a much more convenient and efficient manner. Temperature fields can be interpolated between dissimilar meshes (see “Reading temperatures from a previous analysis,” Section 6.6), which allows you to efficiently perform a sequentially coupled thermal-stress submodel analysis by reading the temperatures from the output database for the global stress analysis, as illustrated in Figure 6–3.
Alternatively, you can read the temperatures from the output database for the global heat transfer analysis, as illustrated in Figure 6–4.References:
