PointWise 18.1 R2

"Our involvement in several American Institute of Aeronautics and Astronautics (AIAA) workshops on CFD has allowed us to learn more not only about how boundary layers should be resolved with the mesh but also about the flexibility our customers need in prescribing boundary layer regions," said Carolyn Woeber, Pointwise's manager of technical support. "Based on what we learned from CFD practitioners and solver authors, we added a feature called Growth Profiles for rapid setup of the boundary layer meshing attributes for our T-Rex (anisotropic tetrahedral extrusion) technique."
Growth Profiles provide a rapid way to compute the meshing attributes for resolving laminar and turbulent boundary layers. Given three simple flowfield parameters, boundary layer theory is used to compute and apply the appropriate growth rate schedule for T-Rex. Advanced users can also create a completely customized cell growth schedule to meet the precise needs of their application that is built from spacing values, the desired number of constant layers, the desired number of accelerated layers, and growth rate acceleration. Some of the technical details for this work can be found in the paper, A Qualitative Study on the Effects of Mesh Guideline Modification for Unstructured Mesh Generation of the NASA High Lift Common Research Model (HL-CRM), by Ms. Woeber and William T. Jones of NASA (AIAA paper no. 2018-3401).
Pointwise Version 18.1 R2 also includes several smaller features and defect corrections. These release notes are provided as a reference for the new features included in the latest version of Pointwise as well as any known issues that were resolved.
- An Average Spacing toolbox has been added to the toolbar.
- Setting the distribution to Tanh or Equal Spacing has been added to the toolbar.
- Custom T-Rex growth profiles are now available when using scripting.
- When a database surface is deleted, the domains that will lose associativity are now reported.

Pointwise is the choice for CFD meshing, covering all aspects of preprocessing from geometry model import to flow solver export. Available for Windows, Linux, and Mac, you can generate structured, unstructured, and hybrid meshes including our T-Rex technique for highly-automated generation of boundary layer resolving hybrid meshes.
Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today - reliably generating high-fidelity meshes. The company's Pointwise software generates structured, unstructured, overset and hybrid meshes; interfaces with CFD solvers such as ANSYS FLUENT, STAR-CCM+, OpenFOAM, and SU2 as well as many neutral formats, such as CGNS; runs on Windows, Linux, and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Manufacturing firms and research organizations worldwide have relied on Pointwise as their complete CFD preprocessing solution since 1994.
