New Software: GiD 7 Mesh Generator Released
Posted Mon September 23, 2002 @04:38AM
Print version Email story Tweet story
Grid Generation Version 7 of the pre and postprocessing program GiD has been released. This software product is widely used to generate meshes for CFD analysis. It supports the following type of mesh elements:
  • Structured/Unstructured triangles/Quads
  • Structured hexas
  • Unstructured tetras
GiD is also a powerful tool for CFD postprocessing

Among others, one of the CFD programs that uses GiD is Tdyn

Visualization: 3D Display Without Special Glasses
Posted Mon September 23, 2002 @03:53AM

Hardware Philips Research is working on an LCD computer-monitor which can display images in 3D without the encumberance of special glasses.

The display is a heady blend of new technology and another childhood favorite: lenticular imaging. Lenticulars are those colorful cards with finely ridged plastic over a color picture that either have a 3-D look or appear to move as you tilt the card from side to side. Those plastic ridges are actually lenses, and they focus on narrow strips of color that make up the images. Multiple images are interlaced beneath the lenses, so that your eyes build different views as your perspective changes.

Philips' innovation applies a lenticular surface to a high-resolution color LCD. The LCD screen displays tightly interleaved slices of several versions of the scene, giving that same sense of dimensional perspective. The demo at Philips Research is compelling. As you sit before the 17-inch monitor, people and objects seem to come to life. Scenes with well-lit foreground objects and a full range of texture and shadow behind the objects work best.

The other half of the equation is converting everyday 2-D images into 3-D images. Philips engineers developed an algorithm to examine each frame and determine which objects are in the foreground by virtue of their brightness, the sharpness of their edges (focus), and their depth.

Application: CFD Improves Heart Pump Design
Posted Tue September 17, 2002 @02:28PM

Application Scientists at Rice University's Mechanical Engineering and Materials Science Department are using distributed-memory parallel computers, CFD codes, and EnSight software from Computational Engineering International to visualize blood flow through LVADs (Left Ventricular Assist Devices). Their goal is to make LVADs more efficient and less prone to clotting.

LVADs are implantable pumps that assist a damaged heart while a patient waits for a transplant. Although the device is buying many patients valuable time, it is still considered experimental. The promise of a better long-term solution has researchers around the world studying LVADs.

Rice's LVAD simulations have enabled researchers to identify and quantify high-shear stress areas that can lead to the device's failure. They have also confirmed experimental observations regarding the persistent stagnation areas that lead to clotting. These results are giving researchers useful clues for improving centrifugal pump design.

CD-adapco The CD adapco Group invites you to a free workshop:

Predicting fuel cell behavior with CFD
October 11th, 10:00 am -- 3:00 pm
Bellevue Hilton
Bellevue, Washington

The keynote speaker will be Professor John Van Zee, of the University of South Carolina. Prof. Van Zee will discuss application of CFD coupled to electrochemistry modeling to PEM fuel cell design and analysis. By coupling electrochemistry models with the advanced CFD capability in CD adapco Group's solver STAR-CD, it is possible to get significant insight into issues such as heat transfer, fluid flow, membrane saturation and electrical current density.
