New Software: New Capability for Analyzing Fluid-Structure Interaction
Posted Wed April 25, 2007 @10:57AM
Print version Email story Tweet story
News Dassault Systèmes (DS), a world leader in 3D and Product Lifecycle Management (PLM) solutions, announces the availability of a powerful coupled-analysis capability for fluid-structure interaction (FSI) utilizing ABAQUS, the technology-leading finite element analysis (FEA) software from their SIMULIA brand, and STAR-CD, a market-leading computational fluid dynamics (CFD) software from CD-adapco.

The new FSI solution builds on the SIMULIA strategy of delivering an open platform for multiphysics simulation. The bi-directional coupling leverages a strong partnership with CD-adapco and the independent, open solution for the coupling—MpCCI software from Fraunhofer SCAI—to enable ABAQUS and STAR-CD to work together to solve a wide range of important FSI problems.

Solvers: Why Use a Panel Method?

Solver Panel methods can calculate the gas or liquid flow around complex 3D configurations, such as aircraft, with relative ease. However, that ease comes at a price: panel methods are incapable of modeling the viscous effects that are evident in all real-world flows. So why would an engineer use a panel method?

Application Getting a new extrusion die to shape a profile that meets design specifications has often been more art than science.

However, the science of CFD is now being used to shorten die-design tasks with die balancing and reverse engineering.

Research: Fluid Dynamics Works on Nanoscale in Real World

News In 2000, Georgia Tech researchers showed that fluid dynamics theory could be modified to work on the nanoscale, albeit in a vacuum. Now, seven years later they've shown that it can be modified to work in the real world, too – that is, outside of a vacuum. The results appear in the February 9 issue of Physical Review Letters (PRL).

Understanding the motion of fluids is the basis for a tremendous amount of engineering and technology in contemporary life. Planes fly and ships sail because scientists understand the rules of how fluids like water and air behave under varying conditions.

News Sharc’s Extreme Mesher, has just been released with improved meshing algorithms.

Months of work behind the scenes has resulted in new optimization algorithms for CFD solvers which may have had convergence problems in the past. The enhanced routines are included in the default settings of Harpoon v 2.5 which also includes an option for ‘super converge’ to help with any particularly difficult geometries.

New Software: EnSight Release Features New Camera Functionality

Print version Email story Tweet story
Post Processing Computational Engineering International (CEI) announced today that its latest release of EnSight includes a sophisticated camera feature, which allows users to create 3-D visualizations with multiple vantage points. The new feature provides users with nearly limitless viewing options and makes its possible to create walk-throughs and walk-arounds, follow trace particles through flows, and simulate real-world test cameras, such as those used in automotive crash tests.

The feature eliminates the need to move a virtual object simply to view it from a different perspective. Users can now view objects from any angle simply by moving virtual cameras around the object on user-defined pathways or by positioning static cameras at any defined point.
