New Software: Free CFD Solver
Posted Thu June 06, 2002 @03:08PM
Print version Email story Tweet story
NASA For limited time, you can receive the 3-D Navier-Stokes solver PAB3D limited edition free of charge. The limited edition will have all the options except it will limit the problem size to 500,000 grid points and the number of distributed computers to 4.

The PAB3D code, which was developed at NASA Langley Research Center, solves the three-dimensional Reynolds-averaged Navier-Stokes equations with a finite-volume formulation on structured multi-block grids. The flow solver has a robust (production quality) two-equation k-epsilon turbulence models with anisotropic algebraic Reynolds stress models. PAB3D also has the capability of modeling standard air real-gas effects. The code is capable of working in multiprocessors and distributed computer systems (CFD on Inexpensive Clustered Computers). This code has been used to simulate complex aerodynamic flow configurations and is currently being used in several national programs.

If you are interested, please fill the download registration form at http://www.eagle.com/demopab3d.html. The PAB3D solver has been tested using several operating systems, such as, LINUX, MAC, WINDOWS, SGI, SUN, and HP.

ANSYS FLUENT Do you need an introduction (or re-introduction) to fluid mechanics, heat transfer and computational fluid dynamics? Fluent Inc. is offering a special two-day course designed specifically for this purpose. The next course offering is July 31-August 1, 2002. The main goal for our Fluid Mechanics and CFD Review course is to help the users of CFD to be more successful by having a more thorough knowledge of the underlying physics and numerical techniques that are present within CFD software packages.

It is assumed that participants will have a technical education and background, but not necessarily an engineering degree. The course will be conducted lecture-style, and the topics will be covered in a general fashion with no particular bias towards any CFD software package.

Visit the course web site for the course description, dates, locations, course fee information, and to register online.

You may also register by contacting Fluentís Training Coordinator, Kelly Carter, at 603-643-2600 or mailto:klc@fluent.com.

Print version Email story Tweet story
News CGNS Version 2.1 has been released.

The specific purpose of the CFD General Notation System (CGNS) project is to provide a standard for recording and recovering computer data associated with the numerical solution of the equations of fluid dynamics. The intent is to facilitate the exchange of Computational Fluid Dynamics (CFD) data between sites, between applications codes, and across computing platforms, and to stabilize the archiving of CFD data.

The new version features some significant enhancements:

  • I/O of user-defined data arrays
  • I/O of linked nodes
  • I/O of chemistry data
  • New FORTRAN 77 examples

The library can be downloaded from the CGNS web site.

Application by Paul Roach, ALSTOM Power UK Ltd.

A world-leading supplier to the energy market, ALSTOM offers its customers a comprehensive range of power generation solutions from turnkey power plants to gas-, steam- and hydro-turbines, generators and boilers. Gas turbine design and manufacture has been undertaken at Alstom's Lincoln site since the late 1940ís, with engine ratings up to the 13MW Cyclone introduced in 1997.

To help maximize powerplant efficiency, the Company uses state-of-the-art CFD methods to design compressor and turbine blading. In addition to in-house software, ALSTOM has also been making use of CFX-TASCflow in the last few years. To date, its main use in the Turbine Department has been to examine secondary and parasitic gas flows, such as can occur in blade cooling passages.

    New Software: WinTherm Lite 6.0 Released
    Posted Thu May 30, 2002 @08:23AM
    Print version Email story Tweet story
    News ThermoAnalytics has released WinTherm Lite 6.0. WinTherm Lite utilizes the same state-of-the-art technology as full WinTherm but with model resolution limited to 2500 thermal nodes, and retails for only US $750. Because the user interface is identical to full WinTherm, WinTherm Lite is a perfect way to begin adding thermal analysis procedures to your standard engineering practice. If in the future you require high resolution models, you can upgrade to full WinTherm or RadTherm and continue working with the same interface and files. Want to know more?
