Automated Meshing and Adaptive Re-meshing at Bombardier

Posted Wed June 24, 2020 @03:53PM

Pointwise released a webinar where Amine Ben Haj Ali, senior engineering specialist from Bombardier, explains the Meshing & Adaptive Re-meshing Server (MARS) which automatically generates meshes.

MARS has been used by engineers at Bombardier to generate over 250,000 high-quality meshes since 2017. MARS automates the meshing process, reduces meshing time, and ensures consistent meshes across geometry variations no matter who is using it.

High-Order Curved Meshes for More Accurate CFD Solutions

Posted Thu August 15, 2019 @05:01PM

Pointwise released the first commercial CFD mesher to generate high-order curved meshes for high Reynolds number flows. The case study, "High-Order Curved Meshes for More Accurate CFD Solutions," explains how it works with today’s new high-order CFD solvers to yield the most accurate solutions possible.

Pointwise and the Evolution of Faster, Easier, More Reliable Automated Meshing

Posted Wed May 22, 2019 @04:48PM

In the case study, Pointwise and the Evolution of Faster, Easier, More Reliable Automated Meshing, learn more about user-independent automated meshing and take a look at the latest meshing technologies under development at Pointwise.

Generating high-quality automated meshes for CFD analysis has been an industry goal for more than 30 years. Meshing solution developers have spent much of those years trying to create user-independent solutions, only to be stymied by the inherent complexities of geometry models, the mesh, and the CFD solution.

How CFD Meshing Time Can Be Reduced by 90 Percent

Posted Fri March 15, 2019 @03:26PM

Pointwise has published the case study, Automatic generation of high-quality meshes using Pointwise and Glyph, which details how Glyph scripts integrated with Pointwise can reduce meshing time from up to 15 hours to one or two and time spent on manual input from 12 hours to a few minutes.

The case study is based on a project that was commissioned by the U.S. Air Force under a subcontract from Bob Haimes, the principal investigator of the AFRL CAPS program, to allow Pointwise to automatically generate high-quality for any Engineering Sketch Pad (ESP) created geometry.

Improve CFD Solution Accuracy With High-Order Meshes

Posted Tue January 22, 2019 @05:35PM

Pointwise has released the webinar High-Order Mesh Generation Using Pointwise.

The webinar addresses the two main challenges tied to the degree elevation of linear elements: boundary conformance and curving of high aspect ratio cells encountered within the boundary layer region and shows how to improve CFD solution accuracy by generating boundary conforming, high-order meshes.

Efficient Meshing for MultiScale CFD Simulation

Posted Wed July 12, 2017 @11:00AM

Multi scale meshing for a traditional structured grid generator is a daunting task. The approach causes the fineness of the refined grids near the smaller geometric features to propagate into the field, thereby unnecessarily increasing the cell count, without bringing any practical computational benefit. In fact, it increases the computational time and also unnecessarily demands larger computational resources.
