ABAQUS 2.4 for CATIA V5 Released

By DE Editors

Dassault Systems (DS; Paris, France and Providence, RI) has announcedthe availability of Version 2.4 of ABAQUS for CATIA V5, a key componentof DS’s  SIMULIA strategy. The SIMULA strategy strives to providescalable simulation solutions and an open framework for performingmultidisciplinary analysis within the PLM (product lifecyclemanagement) process. ABAQUS for CATIA builds on the SIMULIA strategy byintegrating a range of linear and nonlinear FEA capabilities within theCATIA V5 environment. Version 2.4 of ABAQUS for CATIA, says DS,introduces several advanced analysis capabilities, such as dynamicanalysis, self-contact, submodeling, and cyclic symmetry.

Dynamic simulation capabilities based on ABAQUS/Explicit are among theenhancements in ABAQUS for CATIA Version 2.4. Here, a new capabilityenables the definition of very general contact conditions, includingcontact between many or all regions of the model with a singleinteraction definition. Such dynamic analyses, says DS, are well suitedfor large models with relatively short response times and for modelingextremely discontinuous events, such as impacts.

ABAQUS for CATIA provides self-contact modeling to simulate surfacefolding, such as when a complex rubber seal folds over on itself. Sinceself-contact is typically the result of large deformation in a model,it is often difficult to predict which regions will be involved or howthey will move relative to each other. A new capability in Version 2.4enables you to self-contact selected surfaces.

Version 2.4’s new submodeling capability lets you target regions ofinterest for detailed stress analysis, letting you obtain accurate,detailed solutions in a local region. You can target a region with arefined mesh and apply submodel boundary conditions in both mechanicaland thermal steps.

ABAQUS for CATIA 2.4’s cyclic symmetry modeling capability is said toimprove analysis efficiency and reduce model size. Cyclic symmetrymodeling is useful for automotive brake disc analysis or turbomachinerysimulation. With it, you no longer need to model the entire body whenanalyzing a body whose geometry, loads, prescribed conditions, andresponse are symmetric about an axis of revolution. In version 2.4, youcan simply model a repeating sector of the body and set fastened pairsto define the sector boundaries. The software then simulates the restof the unmodeled body.
