Title: New Approaches In Quadrilateral And Hexahedral Meshing
Biography: Yang Liu is an associate researcher in the Internet Graphics group at Microsoft Research Asia. He received his PhD degree in computer science from The University of Hong Kong in 2008, Master and Bachelor degrees in computational mathematics from University of Science and Technology of China, in 2003 and 2000 respectively. After completing his PhD degree in 2008, he worked in the Alice group at INRIA/LORIA as a Post-Doctoral researcher. He joined Microsoft Research Asia in 2010. His research interests span in geometric modeling, computer-aided geometric design, and architectural geometry. His recent work focuses on applying geometric optimization in generating high quality quadrilateral/hexahedral meshes for geometric modeling and architectural construction. His IMR talk will include: 1) Distance function-based quad/hexahedral dominant meshing; 2) Frame-guided all-quad/all-hexahedral meshing.
Abstract: Centroidal-Voronoi-Tessellation (CVT) –based methods have shown their strengths in generating high-quality simplical meshes. Their generalization, Lp CVT also demonstrates its capability in quad-dominant and hexahedral-dominant meshing. In the first part of my talk, I will review CVT-based meshing approaches and discuss their strengths and weaknesses. I will introduce a novel convex-distance-based CVT that is more general than existing CVT-based methods and is capable to produce interesting and useful meshing results.
All-quad and All-hexahedral meshing are difficult and demanded in many applications. Recently frame-guided all-quad and all-hex meshing presents some promising results. In the second part of my talk, I will present my recent work on planar quadrilateral mesh design for architectural geometry which is based on conjugate directional field, and all-hex meshing for a given volume that is driven by a 3D singularity-restricted field.
Title: Mesh Direction: Current application and future meshing needs for aerodynamic simulation at Airbus
Biography: Scott Shaw has a degree in Aeronautical engineering and a PhD in Computational Aerodynamics. He spent 11 years at Cranfield University where he researched and taught computational aerodynamics. At Cranfield his research was motivated by the need to understand high-speed vortical flows and he worked on diverse applications including helicopter rotor aerodynamics, supersonic and hypersonic weapon aerodynamics and motorsport aerodynamics. In 2006 he joined Airbus to co-ordinate the development of the Airbus hybrid structured-unstructured meshing tools. In 2011 he moved to Bremen in Germany from where he now leads the Airbus teams in Filton (U.K.) and Bremen (Germany).
Abstract: Over the past decade there has been a significant change in the role of aerodynamic simulation at Airbus. The use of computational simulation has increased dramatically and is increasingly the primary aerodynamic design means whilst the amount of physical simulation (wind tunnel testing) for conventional configurations has been reduced. In this presentation we explore how Airbus has developed meshing tools and processes to support aerodynamic simulation based design. Drawing on these experiences the talk concludes with an outlook on the future of aerodynamic meshing at Airbus.
