Fluent previews 3Matic-for-FLUENT and TGrid 4.0 wrapping solution

Materialise NV : 29 June, 2005  (New Product)
Fluent Inc., and Materialise, the world leader in software development for rapid prototyping and industrial design applications, preview a new preprocessing solution for Automotive Underhood Thermal Management today to delegates at the bi-annual European Automotive CFD Conference in Frankfurt.
The solution combines a batch geometry preconditioning module, 3Matic-for-FLUENT, custom developed by Materialise, and the new TGrid 4.0 wrapper technology from Fluent Inc. Scheduled for release in late 2005, with final prototypes to be demonstrated at all European and Asian Fluent User Group events throughout 2005, the product is aimed at improving the CFD process of geometry to meshed model for a wide range of applications including UTM.

'The 3Matic-for-FLUENT batch module provides a fully automatic mechanism to convert hundreds of files from mixed geometry sources into a consistent, clean and optimal format for TGrid 4.0's wrapping technology' said Koen Engelborghs, Materialise R&D Manager, adding that, 'An essential part of 3Matic-for-FLUENT is a batch file conversion module that allows you to start with any number of geometry files in native or standard CAD file format (like CATIA, UG, Pro/E, STEP, IGES) or faceted formats (like STL, WRML). Each file is then sequentially loaded and imported into the batch reader, and automatically cleaned and exported into the FLUENT mesh format. The cleanup process ensures that each CAD part is fully connected, of minimal size but with sufficient resolution of details.'

Materialise's triangular meshing technology provides powerful geometry conditioning tools that have been used in Rapid Prototyping successfully for years. The combined Materialise-Fluent solution enables TGrid 4.0 users to work more efficiently in the pre-wrapping process of semi-automatic gap and hole filling using a range of new tools, like Cartesian grid panning, face tracing and plane face creation. The advanced TGrid 4.0 Wrapper technology is equipped with zone, proximity or curvature based size functions to get the optimal mesh distribution at the first wrapping attempt. The fully connected wrapper surface can be redistributed to capture selective, or all, external features in the model. An automatic post-wrapping tool scans the raw wrapped mesh and resolves any unwanted configuration and drastically improves the surface mesh quality. Finally, all of the parts defined in the initial CAD model are recovered into boundary zones with a single click of a button.

'We are dedicated to providing not only the best wrapper approach, but a full UTM preprocessing tool kit built around TGrid 4.0' says Erling Eklund, TGrid Product Manager at Fluent Inc., 'The 3Matic-for-FLUENT preconditioning tool will reduce manual engineer geometry clean-up time by 2 to 5 fold and also reduce file size by up to 5 times. When coupled with the advanced wrapping and industry proven stable hybrid meshing tools in Tgrid 4.0, I believe that this combined solution is an excellent step forward in addressing automotive meshing bottlenecks.'

In addition to the new wrapping technology, TGrid 4.0 is also equipped with a long list of new tools, including extensive boundary intersection capabilities, size function based re-meshing tools, and extended boundary and mesh modify enhancements. Prism layer technology has been improved significantly with automatic proximity/collision detection, sharp corner and dangling wall handling.
