Starting with an existing aircraft geometry, we demonstrate the entire meshing process beginning with the generation of a quad-dominant surface mesh. Areas of high curvature are then resolved, followed by generation of farfield boundaries 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 (anisotropic tetrahedral extrusion), 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.
Released in September, Pointwise V18 has not been out long, but already users are leveraging these productivity enhancements to their advantage. Unstructured viscous meshes generated using our latest T-Rex 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-dominant surface meshing technique—features new in Pointwise V18.
Discover how to:
- Automatically create unstructured quad-dominant surface meshes
- Extrude flow-aligned, hex-dominant boundary layer resolved cells using T-Rex
- Easily generate shapes to define farfield boundaries and sources
- Define off-body volumetric refinement regions using sources
