HEXPRESS : Automatic HEX-meshing made possible!

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.
