Pointwise's Hybrid Meshing for CFD

T-Rex Surface Meshing for Boundary Layer Clustering

The highly automated, hybrid meshing technique for boundary layer flows is now available for surface mesh generation in Pointwise.

The surface meshing formulation of Pointwise's T-Rex technique (anistropic tetrahedral extrusion) is available for automatic generation of layers of high-quality, high aspect ratio triangles in the boundary layer region of flowfields.

Classic Hybrid Meshing via Extrusion

Hexahedral and tetrahedral meshes can be interfaced in several ways to form a hybrid grid. Structured hexahedral and unstructured tetrahedral blocks can be indirectly interfaced by a point to point conformal interface with hanging edges. Direct hex-tet interfaces are created through automatically generated pyramid cells.

Extruded prism blocks interface with tetrahedral blocks either directly (on the triangle faces) or through automatically generated pyramids (on the quadrilateral faces).

Prism layers are created by the extrusion of triangular surface grids following normal, linear, rotational, or user-defined paths with control over extrusion step size or aspect ratio.

Extrusion of prism layers can be performed using a traditional algebraic technique in Pointwise as shown in this video. [1:52]
