Dear Desktop Engineering Reader:
Abaqus FEA from SIMULIA has been a gold standard solution set since before Dassault acquired the company long ago. From the get-go, the idea behind Abaqus has been to get you accurate simulation results quickly, lowering your development costs and speeding time to market. With the introduction of Abaqus 6.9 Extended Functionality (6.9-EF) SIMULIA/Dassault notches it up to another level.
First, a bit of housekeeping. Abaqus/FEA is not designed solely for high-end, ultra challenging nonlinear problems and large-scale linear dynamics applications. It's flexible and adaptable enough for what you might call routine design simulations. The suite is comprised of three main modules – Abaqus/CAE, Abaqus/Standard, and Abaqus/Explicit – and a set of complementary tools that extend its capabilities to such specialized areas as PCB modeling, crash dummy models, and durability prediction. In short, Abaqus/FEA lets you create a multiphysics environment that lets you predict and optimize the behavior of your design in the world where it will operate. Always cool.
The key enhancements in Abaqus 6.9-EF range across its modeling functions to its advanced mechanics features to its overall performance. For example the implicit dynamics procedure has been enhanced to better solve unstable problems involving contact, buckling, and material failure. There's a new iterative solver in Abaqus/Standard that is said to provide up to 20x or more performance gains in comparison to the direct sparse solver. And the company says that creating high-quality surface meshes using the mapped meshing technique has been improved from 2x to 40x.
New modeling features in Abaqus 6.9-EF include interactive support for meshing models, improved tools in Abaqus/CAE offer greater flexibility adjusting geometries in preparation for meshing, and you can even deactivate/reactivate model regions and contact pairs during an analysis. You can now model viscoelastic behaviors with orthotropic/anisotropic elasticity in Abaqus/Explicit, and Abaqus/Explicit's highly regarded fracture and failure modeling capabilities now let you model brittle fracture of partially bonded surfaces.
What this all of this means is that Abaqus 6.9-EF is more capable than ever as well as better performing, which is pretty good for a solution already regarded as highly accurate and high performing. But what this all means for you is that you can get your work done faster and more accurately.

SIMULIA has all sorts of data on graphics, integrations with MCAD software, webinars, and what not that'll give you a complete picture of what Abaqus/FEA can mean for you.
Thanks, pal. --Lockwood
