Simulia parent announces enhanced Abaqus

PROVIDENCE – Dassault Systemes, parent company of Providence-based software firm Simulia, announced the availability of new enhancements in its Abaqus product suite, Abaqus 6.10 Extended Functionality.
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, the company said in a news release on Dec. 2.
“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,” Dassault said, noting the improvements should allow customers across all industries to reduce development time and costs while improving efficiency.
Dassault said that the extended functionality version also provides new contact and mechanics capabilities that improve 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 release also expands on the capabilities of the Extended Finite Element Method in Abaqus, allowing users to predict crack growth due to low-cycle fatigue through thermal analysis of the heating and cooling phase that occurs in an engine exhaust manifold. It also can be used to predict the durability and damage tolerance of composite structures with complex failure mechanisms.
