FOR IMMEDIATE RELEASE
Pointwise, Sculptor and OpenFOAM® Webinar to Feature Automotive Design Optimization
FORT WORTH, TX (25 Aug 2015) - Pointwise and Optimal Solutions will present a webinar entitled “Automotive Design Optimization using Pointwise, Sculptor, and OpenFOAM” on 15 September at 10 a.m. CDT (GMT - 5).

High quality meshing coupled with robust shape deformation techniques enable large design space exploration for optimization without the need to remesh the geometry. To demonstrate this, we introduce a collection of best practices for cleaning complex analytic CAD encountered in the automotive industry and demonstrate a robust meshing technology in Pointwise that can automatically generate high quality boundary layer resolved meshes that retain their quality when morphed by Optimal Solutions' Sculptor during the optimization process.
The case study for this work is the DrivAer model developed by the Institute of Aerodynamics and Fluid Mechanics at the Technische Universität München. Using this geometry, we demonstrate a technique called Solid Meshing to heal faults in the geometry and recover the original engineering intent and when coupled with T-Rex (anisotropic tetrahedral extrusion) enables automated, high quality volumetric grid generation.
Using the DrivAer mesh, we define a set of volumetric shape deformations using few design variables within Sculptor. A technology called Arbitrary Shape Deformation is used to smoothly morph the nodes of the mesh that are inside of the volumetric deformation space. Even for large deformations, this technology can maintain surface boundary layer thickness and orientation.
By eliminating the requirement to remesh after each volumetric deformation, solution changes are minimized and primarily subjected to the changes seen by the OpenFOAM flow results due to model differences. Also, all tools have been coupled to form an automated optimization framework making it possible to find the subtle shape changes that produce large improvements in design performance.

Presenters will be Pointwise's Travis Carrigan and Mark Landon from Optimal Solutions.
Mark Landon is the Chief Technology Officer and founder of Optimal Solutions software. He is the architect of Sculptor, a program for morphing CAD, CFD, FEA, geometry and shape optimization. Dr. Landon holds a Ph.D. in Engineering Structural Mechanics from Brigham Young University (1989). He has also been an Adjunct Professor in Mechanical Engineering and Computer Science at the University of Colorado, the University of Idaho, and Brigham Young University, a Senior Advisory Engineer at the Department of Energy's Idaho National Laboratory (1993 to 2011). Previous employment includes working on the Space Shuttle Main Engines and performing aerodynamics shape optimization of supersonic and hypersonic vehicles for DOD & NASA.
Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today - reliably generating high-fidelity meshes. The company's Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CCM+, ANSYS CFX, OpenFOAM, and SU2 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.
Optimal Solutions' flagship product Sculptor provides innovative, proprietary technology, Arbitrary Shape Deformation, so engineers can deliver improved/optimized designs for many applications in less time than using traditional methods. Sculptor gives the engineer the tools to morph CAD, FEA, multi-physics CAE, CFD, or other geometric numerical models to find those subtle changes that create substantial improvements in design performance. Sculptor has an internal Optimization Control Center or it can be linked to most commercial and governmental optimization codes to fully automate the analysis/optimization process. Design of Experiments with Surface Response Methodology with graphics can be used to quickly explore and visualize the design space. Multiple Disciplinary Analysis and Optimization, fluid structure interaction, Shape Matching, and applying the deformations on the original CAD models are just a few of the areas where Sculptor has been used by many of the world's leading institutions.
