EnSight Used for RAVE Visualization Lab
Posted Mon October 08, 2001 @11:08AM
Print version Email story Tweet story
Post Processing NASA Glenn Research Center has installed EnSight Gold high-end visualization software, from CEI, on Fakespace's RAVE VR system. The system will be used to study the results from turbomachinery analyses including combustion and turbine blade failure.

The RAVE (Reconfigurable Advanced Visualization Environment) consists of 3 8 foot by 8 foot rear-projection screens which can be configured as an 8x24 wall, or as a three-wall immersive environment.

"With EnSight Gold on the RAVE, a detailed model of an intricate structure with many components, such as a jet engine, can be viewed from all angles and diverse vantage points," says Jay Horowitz, visualization manager at NASA Glenn. "We can now bring our data visualizations more 'out of the screen' than before. It is surprising how much better you can understand complex phenomena when you have more control over how you view it."

Why Turbulence Modeling is so Important
Posted Mon October 08, 2001 @10:42AM
Print version Email story Tweet story
Help Desk An article in Scientific American magazine provides an introduction to the simulation of turbulent flows and why the work is essential.

The article starts with a brief introduction to CFD and then progresses to the need for, and difficulty of, simulating turbulent flow. While the article does not go into turbulence modeling in-depth, it does provide readers with a basic understanding of the problems involved and the solutions which have been developed.

The growing popularity of computational fluid dynamics to study turbulence reflects both its promise, which is at last starting to be realized, and the continued rapid increase in computational power. As supercomputer processing rates approach and surpass a trillion floating-point operations per second over the next few years, fluid dynamicists will begin taking on more complex turbulent flows, of higher Reynolds numbers.

New FloWorks Modules Available
Posted Tue October 02, 2001 @05:04PM

News NIKA has announced two new modules for its FloWorks product. The FloWorks software works within the SolidWorks design software allowing for greater integration of CFD in the design phase.

The new FloWorks Basic module provides fundamental fluid flow analysis capabilities such as internal and external flow, incompressible and compressible flow, laminar and turbulent flow as well as steady state flow and heat transfer analysis. The module is priced at $3,995 per seat in North America.

The new FlowWorks PE module expands on the basic module with more control of the mesh and solver settings in order to further optimize analysis effort and computation time. The PE module also includes their novel EFD zooming feature.

EFD zooming allows the engineer to use the analysis results of a complex model as boundary conditions for a local region within the same model. The system will then perform more detailed analysis on the local region (smaller mesh size and tighter convergence criteria). This feature thereby allows the engineer to use a coarse mesh for the entire model and a much finer mesh in the regions of interest.

CFD Visualization in the Classroom
Posted Mon October 01, 2001 @10:20AM
Print version Email story Tweet story
Post Processing The U.S. Air Force Academy has licensed EnSight as a visualization tool for its Advanced Applied Aerodynamics course.
EnSight's ability to plot multiple time-dependent phenomena simultaneously allows us to show students how shock formation and location impact such parameters as lift and drag, says Maj. Doug Blake, assistant professor of aeronautics at the Air Force Academy. We are always looking for new ways to teach students. Several faculty members are involved in CFD research at the Academy, and as we obtain results, we try to incorporate them into the classroom.
It's great to see CFD advancing in the classroom.
