Dear Desktop Engineering Reader:

CFD mavens in aerospace, automotive, power generation,  chemical processing, and similar industries look at Gridgen from Pointwise as a gold standard meshing toolkit vital to generating high-quality 3D grids. Gridgen generates a variety of meshes—structured hex, unstructured tet, and hybrid meshes—on your CAD data pretty much repair-free. You can export your mesh in the native formats of many CFD systems and other solvers. It does such a good job so efficiently that big name exhibitors like CD-adapco, CEI,  Intelligent Light, and Tecplot will be at the Pointwise user group meeting next month.

Among the techniques in the Gridgen toolkit is an advanced feature called anisotropic tetrahedral meshing. Dubbed T-Rex by Pointwise, this is a technique for extruding regular layers of tetrahedra from boundaries. The mesh adjusts to convex and concave regions and colliding extrusion fronts, and T-Rex automatically handles things like concave corners without making you get in there and manually figure out what to do.

And that’s the key to what T-Rex brings to your work:  Through its automation and advanced algorithms, T-Rex can reduce your boundary layer mesh generation time from hours to minutes. And, because the mesh you end up with is so clean and so efficiently prepared for your solver, you get more accurate solutions and more rapid convergence from your CFD simulations.

Today’s Check It Out download has more technical data about T-Rex and what automated boundary layer meshing for CFD could mean for you. A couple of cool images let you see what it can do for you. You’ll also find a link under the download connection to some examples of where Gridgen is being used and how. Good stuff. Check it right away.

Thanks, Pal. — Lockwood
