Webinar on Unstructured Quad & Hex Meshing Using Pointwise

FORT WORTH, TX (28 November 2016) – Pointwise presents a webinar entitled, “Unstructured Quad and Hex Meshing Using Pointwise.”

Watch the webinar at info.pointwise.com/webinar-unstructured-quad-hex-meshing.

In this webinar, we highlight four features available in Pointwise: quad meshing for surfaces, farfield shape creation, unstructured hex meshing for boundary layer resolution, and volumetric sources. Starting with an existing aircraft geometry, we demonstrate the entire meshing process beginning with the generation of a quad surface mesh. Next, areas of high curvature are resolved, then farfield boundaries are generated using the latest shape creation utilities. The same shape creation utilities are then used to define a source that provides off-body volumetric grid refinement to help track flow features of interest. The volume mesh is generated using T-Rex, our unstructured viscous meshing algorithm, which extrudes stacks of flow-aligned hexahedra and prisms that smoothly transition to an isotropic tetrahedral farfield. Lastly, we examine the volume mesh cell quality using several of the many mesh quality metrics available to users of Pointwise.

Pointwise users are leveraging these productivity enhancements to their advantage. Unstructured viscous meshes generated using our latest T-Rex (anisotropic tetrahedral extrusion) meshing algorithm have fewer cells, solutions converge more quickly and robustly, and results are more accurate. Many of these benefits come from applying simple changes to existing grids and taking advantage of the boundary-aligned quad meshing technique.
