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.


Reducing Discretization Error with Mesh Adaptation

Learn how mesh adaptation can improve CFD solution accuracy. Mesh adaptation can automatically add finer mesh resolution in areas where it is needed by examining an error metric or flow gradients to determine where the existing mesh is not adequately resolving the flow.

The Ultimate Guide to Writing Import and Export Plugins

One of the most frequent requests that Pointwise receives is to add native import and export capability for a grid file format. Unfortunately, there are not enough hours in the workday to fulfill all of these requests. For that reason, a plugin capability has been made available so you can easily write your own importer or exporter.

Pointwise Aids Bid to Make World’s Fastest Bike

The Human Power Team is comprised of students with a shared goal: to build a highly advanced recumbent bicycle capable of breaking the world record for the fastest human alive. We will put our bike, the VeloX, to the test for the seventh time in the annual World Human Powered Speed Challenge in Battle Mountain, Nevada. This year the Human Power Team will focus purely on the world record for women, which was set at 121.81 km/h by Barbara Buatois in 2010.

Multi-block Structured Meshing of a Diffusing S-Duct

In this webcast, we use a diffusing serpentine inlet to demonstrate some of the more advanced structured meshing techniques available in Pointwise. These meshing strategies highlight how Pointwise users can generate uniform, boundary-layer resolved grids with exceptional cell shape quality where the inlet’s shape transitions from something with a square cross-section upstream to a circular shape at the exit.

The Stanford Solar Car Project’s Race for Aerodynamic Efficiency

Chasing the Sun 3000 km across the Australian Outback is a challenge. And doing it in a solar powered vehicle is an even bigger challenge. But every two years the Stanford Solar Car Project, a student-run organization, arrives in Australia with a new design ready to take on the Bridgestone World Solar Challenge. This article summarizes the simulation driven design framework that enabled the team to analyze over 40 design iterations and improve the aerodynamic efficiency of their 2015 car, Arctan.
