Pointwise Solutions

for CFD Mesh Generation


You can generate structured multi-block, unstructured, hybrid, and overset meshes for viscous simulations with precise control over point placement and clustering to get the resolution you need. At the same time, Pointwise’s core meshing methods produce cells of high quality to ensure convergence and accuracy in your CFD solution.


Meshing Overview & S-Duct Results from the 3rd Propulsion Aerodynamics Workshop

Pointwise provided a set of standard grids for workshop participants to use at this year's 3rd Propulsion Aerodynamics Workshop in Salt Lake City, Utah. These grids were created using several new features available in Pointwise's upcoming V18 release. An overview of some of these features and the workshop grids is provided. Some initial steady-state results for the S-Duct using these grids and NASA's FUN3D solver are presented.

Automating Geometry and Mesh Generation for Heat Exchangers

Maura Gallarotti, a master's student at KTH Royal Institute of Technology in Sweden, used Pointwise Glyph scripting to quickly generate families of candidate heat exchanger designs and to perform parametric studies by changing the dimensions of several geometrical parameters to assess the effect of these parameters on cooling efficiency. With no experience using Pointwise and having never heard about Tcl/Tk or Glyph she was able to write a script to completely automate the grid generation process in less than a week.

North America’s Largest 3-D Printed Structure Started as a Mesh

While the folks at Pointwise appreciate the beauty and utility of grids, usually the computational meshes produced by our software are used as an intermediate step in a customer’s engineering analysis process and not as the final goal of the project. However, Branch Technology, with its novel freeform 3-D printing techniques actually turns these meshes into physical structures that can be used as building elements or as seen here, works of art.

Revisiting Output-Based Mesh Adaptation

Mesh adaptation techniques in computational fluid dynamics (CFD) applications have matured substantially over the years, yet still few people seem to be leveraging them to their advantage. In this article, some background on why you should be using mesh adaptation to make sure important flow features are resolved without an inordinately large overall cell count is presented along with an example using Pointwise and NASA's FUN3D solver.

High Fidelity Overset Structured Mesh Generation for Marine Hydrokinetic Devices

Researchers at The Pennsylvania State University used the overset grid assembly tools in Pointwise to generate high-quality structured overset meshes for analysis of a horizontal axis water turbine. The flexibility offered by overset grids made it easy for them to add higher resolution grid blocks to resolve regions with high flow gradients like the turbine blade tips, wakes and tip vortices. This resulted in good agreement with experimental data even for flow details like the interaction between blade wakes and the support tower.

Meshing the 24th IMR Fender® Jazzmaster Guitar and the Abdominal Atlas

Last month several Pointwise engineers attended the 24th International Meshing Roundtable (IMR) held in Austin, Texas. We brought two grids generated for two benchmark geometries provided by the IMR steering committee. The grids were made by Carolyn Woeber, Travis Carrigan, and myself. We were pleased to hear that the grids were recognized both for their technical merit and striking visuals - they had won the Meshing Contest award.

Integrating OpenVSP and Pointwise for High-Fidelity CAE in Conceptual Design

Pointwise recently attended the OpenVSP Workshop 2015 hosted by NASA Langley and demonstrated Glyph scripting for automated viscous anisotropic meshing of a transport aircraft from OpenVSP. With recently added support in OpenVSP 3 for exporting models as STEP files, users now have an easy way to use an analytical geometry representation in Pointwise. The Glyph script automates the meshing process and provides a recipe for recommended meshing practices that new users can adopt when creating their own meshes in Pointwise.
