HEXPRESS : Automatic HEX-meshing made possible!
Posted Wed January 30, 2002 @06:53PM
Print version Email story Tweet story
Grid Generation NUMECA International has announced the release of HEXPRESS™, a revolutionary new unstructured, pure-hexahedral, body-fitted mesh generator.

In response to the unanswered need to simplify unstructured mesh generation, while maintaining the accuracy inherent to hexahedral cells, NUMECA has extended its technological advancements to this arena. The initial response for this tool has been so favorable that many new requests are focusing on providing grid output directly for use with a wide variety of other commercial, unstructured solvers.

“HEXPRESS™ represents a revolutionary new concept in automatic unstructured hexahedral grid generation. We are convinced that this tool will drastically reduce your engineering time to produce high quality grids,” states Prof. Charles Hirsch, President of NUMECA International.

A user-friendly, comprehensive, and robust mesh wizard enables rapid, step-by-step grid generation initiated with CAD file importation. A volume-to-surface methodology with automated target mesh sizing rapidly provides an initial grid. Global (and local) mesh refinement can be achieved using surface curvature and/or number of cells between two surfaces as criteria. In addition, a target cell size applied globally or locally can be used to refine the mesh. HEXPRESS™ then automatically snaps the grid points to the CAD geometry and an advanced optimization algorithm is used to maximize grid quality. Finally, clustering is applied near the surfaces to enable the capture of boundary layer effects.

To simplify CAD integration, NUMECA has formed a partnership with CADfix™. The result is a simple and fast file importation for major CAD formats. In addition, a powerful and efficient CAD cleaning tool is available.

No-risk evaluations of the new tool are available.

New Software: Flow Science, Inc. Announces Release Of Version 8
Posted Wed January 30, 2002 @06:50PM
Print version Email story Tweet story
News Flow Science, Inc. announces the availability of a major new release of its FLOW-3D® computational fluid dynamics software. FLOW-3D® Version 8.0 features many new models, functionalities and improvements designed to increase user productivity and capabilities, and is perhaps the biggest leap forward for the well-respected software package in several years.

The most significant new feature is the introduction of the ability to create multiple grid blocks in the design of a simulation. Multi-block gridding in FLOW-3D® will enable users modeling complex flow phenomena to run their simulations faster yet, at the same time, more efficiently use computer resources. Each block will span a certain region of the whole flow domain and contain the standard structured rectangular mesh. Blocks will be able to be nested (one block contained entirely within another block) or linked (blocks are joined at their boundaries). Users will also be able to apply multiple mesh boundary conditions at the domain boundaries.

Using linked blocks, users can reduce problem size (reducing runtimes and saving storage and memory requirements) to create a pattern of flow that is limited to the actual flow domain. Likewise, where a particular area within the flow domain is of most interest to a user, one or more nested blocks of greater resolution can be placed inside a larger block with coarser resolution to allow a higher degree of accuracy of simulation in areas of interest (and again saving running time and storage and memory requirements).

Other major aspects of Version 8.0 are a New STL Viewer; a New General Bubble Model; a New Sediment Scour Model; and a New Dielectric Phenomena Model.

Application: CFD Reduces Design Time from 1 Year to 4 Weeks
Posted Fri January 11, 2002 @02:22PM
Print version Email story Tweet story
Application By adding computational fluid dynamics (CFD) analysis to its product development process, Blender Products was able to design a new HVAC air mixer in four weeks, down from the one year required for its previous mixer. Designing that product had required many rounds of prototype testing, each taking several months, to determine how efficiently the device mixed two streams of air. For the new mixer, the company ran multiple CFD analyses to evaluate different design iterations in software. Each iteration took less than a week. The results guided designers as to what elements could be removed to reduce manufacturing costs while maintaining mixing efficiency. Nearly all prototype testing was eliminated, allowing Blender Products to quickly capitalize on a new market opportunity. The company also uses CFD analysis to evaluate how its mixers will work when added to existing installations. This formerly required testing of a scale model, a process that took two to three months. The company now accomplishes the evaluation without a scale model and is done in one week.
