Dassault Systèmes Accelerates Exploration of Real-World Product Performance with Abaqus 6.10-EF
VÉLIZY-VILLACOUBLAY, France and PROVIDENCE, R.I., USA, December 2, 2010 — Dassault Systèmes (DS) (Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced the availability of Abaqus 6.10 Extended Functionality (6.10-EF), the leading unified Finite Element Analysis (FEA) and multiphysics product suite from SIMULIA, the Dassault Systémes brand for realistic simulation.
As part of SIMULIA’s commitment to provide innovative realistic simulation solutions, Abaqus 6.10-EF delivers a number of powerful, customer-requested enhancements for modeling, visualization, contact, mechanics and performance. These improvements enable customers to reduce development time and costs, while increasing the efficiency of the product development process through highly accurate simulations of real-world product and material behavior.
Among the modeling and visualization enhancements in 6.10-EF is dramatically improved support for substructure modeling capabilities. Abaqus users can now more easily create a substructure of a distinct region in their product, import it into an assembly, recover the results during an analysis, and reuse the substructures in future models, saving significant modeling time.
“The rearview mirror systems we supply to the medium- and heavy-duty truck manufacturers contain a number common internal sub-assemblies, such as actuators, that are used in many different mirror systems,” stated Dr. Rolf de Swardt, chief engineer and FEA specialist at Lang Mekra North America. “The new substructure support capability in Abaqus 6.10-EF allows us to develop very detailed FE models of these components, and then ‘plug’ them into new system models, not only saving us time in constructing the models, but also shortening runtime of the large eigenvalue analyses we typically perform to ensure the mirrors do not vibrate excessively.”
Abaqus 6.10-EF also provides new contact and mechanics capabilities that improve the efficiency and accuracy of simulating real-world performance of designs, including fluid leakage between 3D bodies in contact. For example, uneven pressure applied to a syringe plunger during use can result in fluid leakage between the rubber seal and barrel. Support for 3D pressure penetration loading can now be used with any contact formulation, allowing for higher-fidelity simulation results.
"The goal of our research is to provide customers with the latest data related to polymer materials, rubber compounds and polyurethanes. We are pleased that Abaqus 6.10-EF provides support for pressure penetration loading in 3D models,” said Dr. Oliver Haeusler, head of the CAE department at Freudenberg Forschungsdienste KG. “This feature will enable our team to perform more accurate analyses of membranes or pneumatic seals with applied 3D loads."
The latest release also expands the capabilities of the Extended Finite Element Method (XFEM) in Abaqus, allowing users to predict crack growth due to low-cycle fatigue, such as with thermal analysis of the heating and cooling phase that occurs in an engine exhaust manifold. This capability can also be used to accurately predict the durability and damage tolerance of composite structures with complex failure mechanisms.
"The implementation of the Extended Finite Element Method (XFEM) within Abaqus provides us with a means to calculate stress intensity factors without explicitly modelling the defect,” stated Ian Symington, senior consultant at Serco Technical Consulting Services. “This approach has the potential to save significant time during the mesh generation phase and reduce the prolonged effort usually associated with undertaking fatigue crack growth assessments."
Abaqus 6.10-EF also provides significant performance enhancements, including a new scalable, parallel execution capability within the AMS eigensolver, which significantly accelerates frequency extraction analyses required to study Noise, Vibration, and Harshness (NVH) behavior in vehicles. SIMULIA’s four-core AMS eigensolver is estimated to be 1.5 times faster than competitive solutions.
