Did Immature CFD Technology Kill NASP?
Posted Tue May 17, 2005 @04:53PM
 Print version Email story Tweet story
Application In Why Technology Projects Fail, The Space Review lists the NASP program's reliance on immature CFD technology as a reason for its failure.
At the time the NASP was started, the state of the art in computational fluid dynamics was just not far enough along. Modeling the entire flight regime to orbit both aerodynamically and thermally with the fidelity needed would have strained the high-performance computing capacity available at the time.

Is this accurate? Would this be the case if the project were started today?

New Software: Gridgen Version 15.07 Released

Grid Generation Pointwise, Inc. has released Gridgen Version 15.07. This latest release of CFD meshing software features major additions to Gridgen’s geometry modeling capabilities including trimmed surface creation and IGES export.

The ability to create trimmed surfaces and add or remove edges from trimmed surfaces solves a major problem faced by CFD analysts – how to work with the untrimmed or poorly trimmed geometry that is obtained from a CAD system. “Lost trimming information, due to tolerance issues during translation, is a notorious source of problems for the analyst in the CAD-CFD data exchange” said John Chawner, Pointwise’s president. “With Gridgen V15.07, the trimmed surfaces can be recovered easily using these new techniques.” For the analyst creating entire models within Gridgen or supplementing existing models with new geometry, more complex and realistic models can now be created using trimmed surfaces.

ANSYS FLUENT Fluent Inc., world leader in computational fluid dynamics (CFD) software and services, today announced its contribution to the latest version of the undergraduate engineering textbook by Bruce Munson, Donald Young, and Ted Okiishi; Fundamentals of Fluid Mechanics, published by John Wiley & Sons, Inc.

The book is intended for third and fourth-year engineering students who are interested in learning more about the fundamentals of fluid mechanics. The principles they seek to teach are classical and have been well-established. The book therefore reflects many years of teaching experience by the authors and is built on previous Editions and their introductory courses in fluid mechanics.
