The Pointwise CFD product team is pleased to announce the availability of Pointwise 18.3 Release 1, is the choice for computational fluid dynamics (CFD) meshing, covering all aspects of preprocessing from geometry model import to flow solver export.

Pointwise version 18.3 R1 Release Notes - Date: September 2019

The latest release of Pointwise's computational fluid dynamics (CFD) mesh generation software includes the ability to use regular hexahedra instead of unstructured tetrahedra in regions away from the geometry model. The software's T-Rex (anisotropic tetrahedral extrusion) technique generates layers of hexahedra or prisms near the geometry model for boundary layer resolution. Use of regular hexahedra elsewhere in the mesh can improve the CFD flow solver's rate of convergence and accuracy of the resulting solution. An added benefit is a potential reduction in overall cell count.

Pointwise Version 18.3 also includes several new features that further automate surface mesh generation, the ability for users to define their own keyboard shortcuts, the ability to use point clouds for mesh adaptation, and more.

New Features

- Hex-Core meshing is now available. This can be used on existing blocks or to create a farfield.
- Pointwise Viewer is now available and comes bundled with the standard installation. It can be used without a license to examine meshes in any format that can import into Pointwise.
- Keyboard accelerators can now be customized.
- A new T-Rex boundary condition based upon turning angle has been added.
- A new default boundary condition for T-Rex called Auto is now available. Specifically created for the Apply T-Rex feature, this applies an Angle boundary condition if one is specified. If no angle is specified, then it will apply a Wall boundary condition unless the connector is shared by a structured domain, in which case an Adjacent Grid condition is applied.
- The current Pointwise session can be automatically journaled as a session transcript.
- A View Magnifier has been added to allow localized magnification within the display
- Quilt boundaries can now be assembled in the Create, Assemble, Quilts feature.
- Explicit boundaries can now be selected in Create, Patch.
- MeshLink files can now be exported alongside CAE files.
- A T-Rex preference checkbox has been added to Grid, Sync Spacings.
- Curvature clustering now works for Advancing Front Ortho domains with and without mixed cells.
- New Min./Max. Edge Length settings are available for domains.
- Point cloud sources can now be imported using Grid, Import.
- A new distribution type for Connectors, Automatic, has been added. The dimension and distribution of the grid points is based upon the size field.
- The Examine window has been simplified to allow quicker access to the most commonly used features.
- A turntable style rotation (rather than trackball) is now available.
- Jacobian is now available as an Examine function for domains.
- Quad dominant domains now have lower area ratios.

Pointwise is a software system for the generation of two-dimensional (2D) and three-dimensional (3D) grids. Many of the grid generation methods used in Pointwise were developed and fine-tuned over the past 25 years in Pointwise's predecessor, Gridgen. Pointwise combines the grid generation expertise and history embedded in Gridgen with more modern software engineering and graphical interfaces to make grid generation as simple as possible.

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.

In this video, we demonstrate how to use the online user manual. Great detail is provided on various features intended to maximize manual utility.

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.
