Business: MCAE Industry Consolidation Under Fire?
Posted Fri July 12, 2002 @06:19PM
Print version Email story Tweet story
News In 1999, MSC.Software purchased Universal Analytics Inc. and Computerized Structural Analysis & Research Corp., two competitive sources of NASTRAN software who held only modest market share.

In October 2001, the Federal Trade Commission (FTC) challenged the acqusitions on the grounds that they substantially lessened competition and tended to create a monopoly in the relevant markets. The allegations gained end-user support when MSC.Software increased the license fee of its NASTRAN software following the acquisition.

Recently, MSC.Software and the FTC came to an agreement, heading off an administrative hearing scheduled to begin Tuesday in a Washington D.C. federal court.

MCAD Cafe has posted an informative article on the whole event which contains further background.

After following these events, the question becomes, when the CFD software industry inevitably follows the same path of consolidation, will the FTC take issue?

Grid Generation: Researcher Awarded for New Mesh Refinement Strategy

News NASA's NAS Division researcher Michael Aftosmis and colleague Marsha Berger, professor and deputy director of Courant Institute, New York University, have received the American Institute of Aeronautics and Astronautics (AIAA) best paper award for 2002.

Their paper, “Multilevel Error Estimation and Adaptive h-Refinement for Cartesian Meshes with Embedded Boundaries” describes the team’s development of new techniques for error estimation and adaptive refinement for computational fluid dynamics (CFD) solutions.

Several features put this new h-refinement strategy a cut above previous adaptive meshing techniques: “It is general enough that it can be applied to any type of unstructured or hierarchical mesh, and, since it is parameter-free, it can be fully automated,” explains Aftosmis. The new meshing strategy was also designated to remove the dependence on user skill, making it quick and easy to generate meshes.

Aftosmis and Berger plan to integrate these error estimation and refinement techniques into their grid generation and solution software package, Cart3D this fall.

Features: CFD Increases Reliability for Caterpillar
Posted Mon July 08, 2002 @10:23AM
Print version Email story Tweet story
Application Hydraulics is playing an increasingly important role in the performance of heavy equipment and as such, the reliability and effectiveness of hydraulic systems is becoming paramount. Caterpillar was the first company to investigate and use hydraulic systems within the engines of its larger vehicles. Most recently, the company has been using computational fluid dynamics (CFD) to make vital adjustments to some of its hydraulic systems.

Caterpillar aims to design and manufacture superior hydraulic components, supported by high quality system maintenance and service, and its vehicles are renowned for their performance and reliability. So when it became clear that there was a problem with some of its larger vehicles, Caterpillar pulled out all the stops to find a solution.

Visualization: New Volumetric 3-D Display
Posted Wed July 03, 2002 @05:30PM
Print version Email story Tweet story
Hardware Actuality Systems has been raising some interest lately in their spherical display. In the roughly 10-inch diameter sphere, data is displayed using their volumetric 3-D display technology.

The display allows for 360-degree all-around viewing for multiple people. Recently, the US Army Research Lab has undertaken a project to determine the potential for the technology in the military simulation field.

There are several basic volume rendering methods. Actuality Systems uses a translucent screen, spinning at 730 rpm onto which 2-D slices of the 3-D model are projected. The result is a convincing, interactive, colorful 3D image that can be seen from any angle in the room.

Currently, displays such as this one cost around $50,000 US. However, as the cost drops, we may begin to see this technology in CFD visualization.
