Print version Email story Tweet story
News RAND Worldwide has announced [pdf] that it has concluded a master distribution agreement with a division of The Boeing Company to sell and support a broad variety of software applications developed by various divisions of Boeing, the world’s leading aerospace company.

In addition to sales, RAND Worldwide, which is a leading global provider of engineering solutions and Product Lifecycle Management (PLM) services and solutions, will be responsible for marketing, collateral material development, documentation, and packaging of the software. The Company will also provide users with complete implementation support, including curriculum development and training services. RAND Worldwide’s partner, Incorporated, developer and owner of the online resource and business for engineers, will provide e-business support for Boeing as well.

Research: New Algorithm Speeds Fluid Simulations
Posted Mon February 02, 2004 @05:29PM

News Researchers at the University of Illinois at Urbana-Champaign have developed a geometric cluster algorithm that makes possible the fast and accurate simulation of complex fluids.

Computer simulations play an essential role in the study of liquids that contain particles of different sizes, which are commonly known as complex fluids. But the two main techniques for the atomistic simulation of liquids - the molecular dynamics technique and the Monte Carlo method - have limitations that greatly reduce their effectiveness.

'The main advantage of the molecular dynamics method - its ability to provide information about dynamical processes - is also its main limitation,' said Erik Luijten, a professor of materials science and engineering at Illinois. 'Many complex fluids contain particles of widely different sizes, which move at vastly different time scales. A simulation that faithfully captures the motions of the faster as well as the slower particles would be impracticably slow.'

New Software: Low Cost CFD Program Available

News A new low cost CFD program which simulates gas and liquid flow in 3D is available from Raczynski Consulting.

Fluids4 solves the Navier-Stokes (N-S) equation for a gas or an incompressible liquid that flows through 3D channels with obstacles. The channel and the obstacles can be arbitrary 3D shapes. Optionally, the channel may be axisymmetric.

Fluids4 can import STL ASCII files created by CAD/CAM software or other 3D graphics programs. So, you can import a duct or obstacle shape instead of editing it with the Fluids4 shape editor. The "slicer" algorithm of Fluids32 converts an STL file in up to 100 slices that define the 3d duct shape.

Grid Generation: Surface Wrapping Capability Drastically Reduces Meshing Time
Posted Fri January 30, 2004 @10:05AM

News The CD adapco Group, leading provider of advanced computationally-based engineering solutions, announces a unique capability for surface wrapping in its CFD (Computational Fluid Dynamics) software STAR-CD.

When preparing a model for a CFD analysis, surfaces need to be closed in order to generate mesh. The process of surface wrapping therefore typically involves taking raw CAD data, closing holes in geometry, joining disconnected surfaces, removing interior and overlapping surfaces. The surface wrapping capability in pro-STAR, the pre- and post-processing package for STAR-CD, automatically ‘shrink-wraps’ a closed surface mesh made of triangles and/or quadrangles onto the geometry. The engineer simply takes the model, which can be an assembly of various sources such as native CAD (CATIA V4, CATIA V5, Unigraphics, Pro/ENGINEER), IGES, STEP AP203 ISO Standard, Parasolid, STL (Stereolythography), VDA-FS and NASTRAN formats and then shrink-wraps the surface.

News CFD Research Corporation (CFDRC), the leading provider of Computational Fluid Dynamics (CFD) and Multiphysics Software, announced today the spin-off of its commercial Software Products Division. Six products (including CFD-ACE+ and CFD-FASTRAN) and the associated intellectual property assets, personnel, and facilities have been acquired by ESI Software, the leading supplier of PAM-CRASH, PAM-STAMP, virtual prototyping, and manufacturing processes software.

The two companies also established a collaborative development initiative, which will provide the most versatile and comprehensive simulation capabilities for a wide range of industries, including Automotive, Aerospace, Biomedical, Biodiagnostics, Fuel Cells, Materials, Microfluidics, MEMS, Plasma, and Semiconductor Equipment and Processes.

The transaction was completed on 21 January 2004 and included notably software products together with all intellectual property assets, personnel, and facilities as well as customer base and all related commercial rights.
