Dassault Systèmes has announced Abaqus for Catia v5 version 2.4 software for finite element analysis within the PLM process. This is the latest release from Simulia, the Dassault Systèmes brand responsible for developing simulation solutions.
Version 2.4 introduces some advanced analysis capabilities, such as dynamic analysis, self-contact, sub-modelling and cyclic symmetry. The tight integration between Abaqus and Catia v5 allows product design engineers and expert analysts to use the same FEA methods and models,.
Dynamic simulation is based on Abaqus/Explicit analysis which is well suited to large models with relatively short response times and for modelling extremely discontinuous events, such as impact. A new capability enables the definition of very general contact conditions, including contact between many or all regions of the model with a single interaction definition.
Self-contact modelling simulates surface folding. Self-contact is typically the result of large deformation in a model, such as a complex rubber seal that folds over on itself.
Sub-modelling targets regions of interest for detailed stress analysis. When analysing large, complex models such as automotive engines or transmission housings, it is often important to focus on specific, critical areas of the model. A new sub-modelling tool makes it easy to obtain accurate, detailed solutions in a local region
Cyclic symmetry modelling improves analysis efficiency and reduces model size – especially useful for brake disc analysis or turbo machinery simulation.
Our picture shows how version 2.4 can simulate non-linear loads, such as the sag of a car door as it swings on its hinges. The model includes shell, beam and solid components fastened using a combination of spot welds, seam welds and mechanisms.
