SIMULIA (Providence, R.I.), a unit of Dassault Systémes (Paris, France), has released version 6.7 of ABAQUS, its finite element analysis (FEA) software suite. It includes new architecture for high-performance linear dynamics, advanced capabilities for composites simulation and nonlinear materials modeling, a customizable user interface for accelerated model building and results visualization, and two new interfaces for CAD associativity. The new linear dynamics architecture reportedly is fully integrated with existing nonlinear capabilities, enabling the sharing of model data. It also provides what the manufacturer says is the industry’s only unified simulation environment for general purpose structural integrity, powertrain durability, noise and vibration behavior, crashworthiness, occupant safety and tire-roadway interaction. The company also reports that new materials capabilities in this version have been designed specifically for complex composite materials. Finally, a new CAD associative interface has been designed such that loads and boundary conditions are retained between design changes.
