New Software: Latest Gridgen Release Features Mac Port, Improved Meshing
Posted Mon January 03, 2005 @04:14PM
Print version Email story Tweet story
News Pointwise, Inc. has released Gridgen Version 15.06. This latest release of CFD meshing software features a port to the Mac OS© X operating system and a major new capability for mesh extrusion techniques.

The Mac port was strongly motivated by NASA customers who have begun using Macs for CFD meshing, postprocessing, and visualization. Mac OS X and Xserve provide a powerful and productive environment to handle the compute-intensive tasks and support workgroup data needs, while the Power Mac G5 is a desktop machine that people enjoy working with.

Dr. Craig Hunter, a CFD researcher in the Configuration Aerodynamics Branch at NASA Langley Research Center, has this to say about Gridgen and the Mac: "I look forward to Gridgen filling that critical need as a preprocessor tool, and enabling us to more effectively use our numerous structured grid flow solvers and other CFD tools on Mac OS X."

News Fluent Inc., world leader in computational fluid dynamics (CFD) software and services, and Harvard Thermal, the industry expert in the use of ECAD-based interfacing for the creation of detailed component and board level thermal analysis, have entered into a technology licensing agreement to embed Harvard Thermal’s PTD product into Icechip, a detailed thermal design software for IC packages to add to Fluent’s suite of tools for electronics design and analysis that include Icepak, Icepro, Iceboard, and Icemax.

“Icepak division of Fluent is focused on delivering the best-in-class suite of design tools to the electronics industry” says Prabhu Sathyamurthy, Director of Icepak division. “This partnership between Fluent and Harvard Thermal will benefit customers seeking detailed thermal design of IC packages, which are becoming increasingly complex in functionality and layout. Icechip is designed to perform detailed thermal analysis inclusive of IC package substrates, traces, vias, non-uniform heat generation, wire bonds, and solder balls. It will also be able to handle all varieties of IC package types including wirebond and flipchip BGAs, stacked die configurations, and Multi-Chip Modules (MCMs).”

News ANSYS Germany and FZ Rossendorf are announcing the 3rd Joint CFX & FZR Workshop on Multiphase Flows [pdf]: Simulation, Experiment and Application to be held in Dresden, Germany on May 31 - June 3 2005

Keynote speakers will be M. Ishii, M. Lopez de Bertodano, M. Sommerfeld.

More information and registration are available via email at

Multiphase flows are of great interest to a large variety of industries. The power generation, nuclear reactor technology, food production, chemical process, aero-space and automotive industries are all driving forces in this physically and phenomenologically complex field.

The goal of the conference is to bring together experimental and numerical practitioners, and foster discussion and exchange of knowledge between the two sides.

New Software: New Version of STAR-CD Enhances Engine Modeling

News CD-adapco announces the latest release of its world leading computational fluid dynamics (CFD) code, STAR-CD v3.24 which is packed full of new features aimed directly at the engine modeling community.

ECFM models

The eagerly anticipated Extended Coherent Flame Model [pdf] combustion models (ECFM and ECFM-3Z) extend CFD combustion modeling beyond the usual single mixture regime restriction of traditional combustion models. The ECFM models are equally valid whether the charge is "pre-mixed", "partially-mixed" or "non-mixed" or any combination of these.

Jointly developed by Renault and IFP (Institut Francais du Petrole), the ECFM models are intended to address the specific combustion challenges posed by Direct Injection (DI) engines. Unlike traditional Port Fuel Injection (PFI) engines DI engines are characterized by a high degree of charge stratification. Standard models (such as the original CFM model), which require a homogeneous charge, are therefore not easily applied to DI engines. The ECFM models are not subject to this restriction and are valid in all mixture regimes, from very lean through to very rich. The models are equally applicable for GDI engines (using a spark ignition model) and for HCCI and DI Diesel engines (using an auto-ignition model).
