Pointwise to Host Live Q&A Session on Structured Gridding

FORT WORTH, TX (15 January 2014)—Pointwise is hosting a live question-and-answer session on YouTube on 29 January to answer questions and provide more details about a prerecorded video of structured grid generation for an aneurysm. The video will be available for viewing at 10 a.m. CST (GMT -6) on 29 January, with the live question-and-answer session taking place simultaneously via the comments section on YouTube. To participate, go to www.pointwise.com/videos.

The scripts used in creating the mesh also will be available at www.pointwise.com/videos.

The video details the process for creating a high-quality, multiblock structured volume grid on an aneurysm – a complex organic shape.

Creating a fully structured grid on a complex organic shape can be a difficult task. Because of the smooth surface shape, it requires a bit of creative thinking and specialized tools to define a mesh topology with good orthogonality and little skew. Pointwise makes it possible to quickly build a high quality structured hexahedral mesh, while also giving complete control over grid spacing and cell quality.

The geometries were provided by Dr. Gabor Janiga at the Otto von Guericke University Magdeburg (www.ovgu.de/isut/LSS/CFD/CFD_Challenge.html) as part of a challenge in which participants were encouraged to use computational fluid dynamics (CFD) tools to predict which of the two models had a higher probability of rupture.

The Pointwise video demonstrates how to create a multiblock structured volume mesh for one of the aneurysm geometries. Results from the challenge are being prepared by Dr. Janiga for publication early this year.

The video will demonstrate how to
•  Efficiently work with discrete geometry
•  Quickly generate O-H topology for circular geometry
•  Greatly improve cell quality using the elliptic solver
•  Expedite repetitive tasks with scripts
•  Inspect grid quality using various Examine metrics

Pointwise engineers Travis Carrigan and Dr. John Rhoads will participate in the question-and-answer session.

Mr. Carrigan joined Pointwise as a senior engineer after completing his M.S. in aerospace engineering at the University of Texas at Arlington in May 2011. He interned at Pointwise beginning May 2008, producing demonstration and application videos and working in technical support, doing grid projects and quality assurance testing. He received his B.S. in aerospace engineering in 2009 from UTA.

Dr. Rhoads completed his Ph.D. in plasma physics at Princeton University in 2013 and joined the Pointwise staff as senior engineer on the Sales and Marketing Team. Dr. Rhoads' dissertation topic was “Experimental Study of Magnetohydrodynamic Effects and Heat Transfer in Free-Surface, Flowing Liquid Metal.” He earned an M.S. in astrophysics from Princeton in 2009 and B.S. degrees in physics, engineering and mathematics from Texas Christian University in 2007.

Pointwise, Inc. is solving the top problem facing engineering analysts today – mesh generation for computational fluid dynamics (CFD). The company’s 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), and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Large manufacturing firms and research organizations worldwide rely on Pointwise as their complete CFD preprocessing solution.
