FEA software package
Dassault Systèmes has announced the availability of Abaqus 6.9,
its unified finite element analysis (FEA) product suite from SIMULIA.
Dassault Systèmes’ (Paris, France and Providence, R.I.) Abaqus 6.9, a unified FEA product suite from SIMULIA, reportedly delivers new capabilities for fracture and failure, high-performance computing, and noise and vibration. Notable features: The Extended Finite Element Method (XFEM) has been implemented in Abaqus and provides a tool for simulating crack growth along arbitrary paths that do not correspond to element boundaries. The method can be used with other Abaqus capabilities to predict the durability/damage tolerance of composite aircraft structures and assists in evaluation of the onset and growth of cracks in pressure vessels. The general contact implementation feature offers a simplified and automated method for defining part contact interactions in a model, reportedly improving modeling efficiency for complex assemblies. A new co-simulation method enables users to combine the Abaqus implicit and explicit solvers into a single simulation, substantially reducing computation time. And a new viscous shear model allows the simulation of non-Newtonian fluids, such as molten polymers.
