New Microfluidic Disposables Developed with CFD
Posted Mon August 27, 2001 @10:56AM
Print version Email story Tweet story
Application Microfluidic disposables for cellular and chemical detection (sometimes called "lab on a chip") are becoming popular as a way to simplify and speed medical analysis. The systems typically consist of a small (credit card sized) microfluidic device connected to a larger desktop-sized analysis unit. Micronics is developing a disposable total-analysis chip which can handle all of the analysis steps on a chip.

The new chips use a laminate design which permits construction of 3-dimensional microfluidic structures, such as, focusing channels for cell analysis. Micronics is using CFD for design and analysis of the focusing channels in order to determine the complete pressure and velocity fields and to predict the dimensions of the core stream.

The results and comparision with experiment are available in this pdf file.

Print version Email story Tweet story
Post Processing CEI, makers of the visualization software EnSight, are releasing EnLighten and EnVideo free of charge on their web site.

EnLighten is a player which allows others to see your EnSight visualizations across the network.

EnLiten users can manipulate 3D models, view models and animations from different perspectives, and run a variety of 3D animations provided by EnSight users.

EnVideo plays a proprietary video format (evo) which offers better quality than AVI and MPEG video formats. The player can be embedded in MS Powerpoint, Internet Explorer or Netscape for presentations.

CFDRC Unveils Fuel Cell Design App
Posted Fri August 17, 2001 @03:12PM
Print version Email story Tweet story
News CFDRC is showing [pdf] a prototype design application for fuel cell stack optimization. The application follows the current trend of tailoring a CFD program to match the expertise of the end user. In the case of the fuel cell program, the input parameters are defined in terms customary to the engineer without a need for in-depth CFD knowledge.

The package handles geometry generation, mesh generation, model definition, computing the solution, and post-processing - all in terms familiar to the design engineer.

Most impressive is the ability to define custom "cost" functions for automatic optimization of the fuel cell stack. Several cost functions can even be combined for multi-dimensional optimization.

News Rick Matus writes "Pointwise Releases Gridgen for Linux Fort Worth, TX, August 20, 2001 - Pointwise today released Gridgen, their mesh generation and pre-processing software for computational fluid dynamics (CFD), for the Linux operating system.

"We're very excited about the Linux port of Gridgen" said Dr. John Steinbrenner, Pointwise's Vice President of Research and Development. "CFD engineers had submitted more requests for Linux than any other hardware platform." Gridgen's Linux port uses the most up-to-date drivers from graphics accelerator vendors to provide OpenGL hardware acceleration.

Scott Percival, a Gridgen for Linux Beta tester at the U.S. Navy Surface Warfare Center's Carderock Division, wrote that "I had all the power and capability of Gridgen on my PC without having to give up Unix" Another Beta tester at Lockheed Martin wrote that "We were very pleased with the Beta version and eagerly await the shipping version of Gridgen for Linux."

Gridgen is a meshing application for CFD that generates hexahedral, tetrahedral, and hybrid (prisms and pyramids) meshes. The software runs on the 5 major Unix platforms, Linux, and Windows operating systems. Gridgen is a complete meshing application and includes trimmed-NURB geometry import from CAD systems, meshing tools, and direct interfaces to CFD solvers such as Fluent, STAR-CD, and CFX. Gridgen reduces meshing time through:

  • Fault tolerant,"repairless" meshing of sloppy CAD models
  • High quality mesh cells - leading directly to high accuracy simulations
  • Responsive and knowledgeable tech support

Further information on Gridgen can be obtained from Pointwise's web site,
