Dassault Systèmes (Paris, France and Providence, R.I.) has released Abaqus 6.9 Extended Functionality (6.9-EF), its unified finite element analysis (FEA) product suite from SIMULIA. New features and enhancements include interactive support for meshing models, using cylindrical elements; geometry repair tools that offer greater flexibility and broader scope for systematically adjusting the model geometry in preparation for meshing; discrete orientations that provide a method for defining spatially varied material orientations on models with curved geometries, such as aircraft panels and car bodies; and modeling of viscoelastic behavior with orthotropic/anisotropic elasticity, which provides more realistic composite damage prediction. Additionally, the new version introduces a new method for analyzing structures that are subject to air-blast loading, and the software also reflects continued advancements in fracture and failure. These include contour integral evaluation for cracks, defined with XFEM. Further, the Virtual Crack Closure Technique (VCCT) is packaged in Abaqus/Explicit, which enables users to model brittle fracture of partially bonded surfaces. A new iterative solver in Abaqus/Standard provides performance gains up to 20 times or more in comparison to the direct sparse solver.
