Announcements Pointwise will host a free, hour-long webinar titled Automating Viscous Meshing for a Transonic Aircraft Model Using Glyph Scripting at 11 a.m. CDT on 5 October.

The webinar will illustrate how to use Pointwise’s scripting language – Glyph – to cut turnaround time by enhancing the reliability and repeatability of the meshing process through automation.

The webinar will be presented by Dr. Chris Sideroff and Travis Carrigan. Dr. Rick Matus will be the moderator and Nick Wyman will participate in the webinar question and answer session.

Meshing strategies will be demonstrated for the NASA Common Research Model, a geometry with typical transport aircraft characteristics, from the 4th AIAA Drag Prediction Workshop.

Being able to accurately obtain force and moment coefficients is crucial to the prediction of an aircraft’s behavior and ultimately its performance. This involves simulating an aircraft during different phases of flight and various configurations. Reliably completing such complex simulations does not rely on computational hardware alone, but also on mesh quality and the amount of time spent in meshing. This webinar will explain Glyph scripting techniques that address these two important factors in the mesh generation process.

The webinar will demonstrate reliable meshing automation strategies using Glyph and show how to create procedures for commonly used grid operations. It will explain how to save time writing code by journaling integral parts of the meshing process and how to drive grid resolution by parameterizing key variables.

To register for the webinar, go to www.pointwise.com/webinar/. Openings are limited, so early registration is advised.

Dr. Sideroff joined Pointwise in September 2007 after working as a petroleum engineer for the NATCO Group, a CAD engineer for ARV Development, and a computer technician for Harddata Ltd. Dr. Sideroff earned a B.S. and M.S. in mechanical engineering from the University of Alberta and a Ph.D. in mechanical engineering from Syracuse University in 2009, where his dissertation subject was “Detailed Examinations of the Human Micro-Environment by CFD.” He is a technical sales engineer at Pointwise.

Travis Carrigan joined Pointwise as a technical sales engineer after completing his M.S. in aerospace engineering at the University of Texas at Arlington in May 2011. He interned at Pointwise beginning in May 2008, producing demonstration and application videos and working in technical support, doing grid projects and quality assurance testing. During a prior internship at Vought Aircraft Industries, Mr. Carrigan worked as a quality engineer on the Boeing 787 Dreamliner Program. His thesis subject was “Aerodynamic Shape Optimization of a Vertical Axis Wind Turbine.” He received his B.S. in aerospace engineering in 2009 from UTA.

Dr. Matus, vice president of sales and marketing, joined Pointwise during its first year of operation. Previously, he was product manager for the RAMPANT computational fluid dynamics (CFD) solver, predecessor of Fluent, at Fluent, Inc. and for several years supervised and performed applied CFD at General Dynamics Fort Worth Division. Dr. Matus earned a Ph.D. in aerospace engineering from the University of Texas at Arlington in 1986.

Nick Wyman directs Pointwise's research efforts, focusing contracted software development on solving problems faced by our customers. He joined Pointwise in 1998 as a Gridgen developer and became manager of the Development Team. He received a B.S. in aerospace engineering and a M.S. in mechanical engineering from Texas A&M University in 1992 and 1994. Before joining Pointwise, he worked for Advanced Scientific Computing (later AEA Technology), performing CFD applications work and developing grid generation software for turbomachinery.

Pointwise, Inc. is solving the top problem facing engineering analysts today – mesh generation for CFD. The company’s Gridgen and Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CCM+, ANSYS CFX and OpenFOAM as well as many neutral formats, such as CGNS; runs on Windows (Intel and AMD), Linux (Intel and AMD), Mac and Unix, and has scripting languages that can automate CFD meshing. Large manufacturing firms and research organizations worldwide rely on Pointwise as their complete CFD preprocessing solution.
