Fidelity Pointwise 2022.2 is here and there are a variety of new features and enhancements to efficiently generate meshes for fast, high-fidelity CFD computations. In particular, we want to showcase for you High-Performance Grid Elevation, Automatic Surface Mesh Improvements, and Improved Efficiency for Unstructured Block Smoothing.
The next generation of high-order flow solvers requires high-order meshes. High-order grid elevation is now more fully integrated into the Fidelity Pointwise workflow under the Grid menu. New in 2022.2 is the ability to export mixed-order meshes in a variety of CAE formats without leaving the meshing task. And, thanks to new performance enhancements, mesh elevation is 2X-15X faster than in Pointwise 2022.1.
Mixed-order mesh containing linear (green), quadratic (yellow), cubic (pink), and quartic (blue) elements. Note that regions of high curvature are captured with higher-order elements while regions with less curvature require lower-order elements.
When generating a surface mesh with Automatic Surface Mesh (ASM), it is often the case that geometry features cause unwanted clustering of cells, resulting in over-refinement of the resulting 3D mesh and excessive computation time. New improvements to the ASM workflow make it easier than ever to create and edit filters and there are several new controls that users now have available to address cell distribution. You can:

Unstructured block smoothing is now significantly faster due to new performance enhancements. Cell quality can now be improved on average 5X-7X faster than previous versions, with speedups up to 10X faster in some cases. This brings block smoothing time down from hours to minutes. By running the smoother in multiple passes with a few iterations per pass, smoothing can be achieved as quickly as possible, resulting in a high-quality mesh for optimal CFD computations.
Unstructured block smoothing speedup from Fidelity Pointwise 2022.1 to 2022.2 across a variety of cases.
All these features and more are available to you in Fidelity Pointwise 2022.2. Download it today.
Pointwise 2022.2 is identical to Pointwise V18.6 R4 for those customers still using the legacy version using RLM for license management.
