The 21st IMR will have an hour and fifteen minutes professional development session targeted towards students and postdocs. This is a discussion type session where six panel members, who are experts from academia, industry, and labs, address questions from the audience and session chair. The potential topics include forthcoming trends in meshing, desired skill-profile for university/industry/lab jobs, impact of alternate methods (meshless methods, isogeometric analysis, etc.), meshing jobs growth in currently economy, etc.
Panel Members are as follows:Dr. Scott Canann - CD-adapco
Scott got his PhD in Civil Engineering in 1991, where he did meshing research funded by Sandia Labs in the areas of automatic hex meshing and optimization-based smoothing. It turns out that he was one of the first Cubit developers, since Cubit was started near the end of his PhD. The 1st Meshing Roundtable started when Scott went to update Ted Blacker (his Sandia adviser) on his PhD research and we invited other meshing researchers to join us. His first job after his PhD was with PDA Engineering (soon thereafter bought by MSC) in Orange County California working on Patran meshing development. Some of his areas of focus there were to develop the first topological cleanup techniques for triangle and quadrilateral meshes. He also did some of the first commercially developed work on optimization-based smoothing. In 1995 he left there to got to ANSYS, where he headed up the meshing team. He also worked as an adjunct professor at Carnegie Mellon University, overseeing PhD and MS students on their meshing research. While there, the meshing team developed a whole new suite of meshing tools, including triangle, quad, swept and tet meshers. In 1999, Scott left ANSYS to work for 11 years doing meshing development for a start-up company called Object Reservoir in Austin, TX. Then in 2010, Scott joined CD-adapco as a senior meshing developer, working on things like surface meshing on tessellated surfaces, automated mapped meshing, and sweeping.
After graduating from Cambridge University, David Martineau joined the Computational Aerodynamics Department of the Aircraft Research Association (ARA) in June 1999. At that time, the hybrid multi-block CFD system SAUNA (Structured And Unstructured Numerical Analysis), developed by ARA under MoD funding, was reaching maturity. He was involved in generating meshes for a number of projects using SAUNA, as well as making enhancements to the mesh deformation capability. At the same time, Airbus, ARA, BAE SYSTEMS, and QinetiQ began collaboration on a new CFD system for rapid Navier-Stokes analysis of external aerodynamics configurations. The new system, SOLAR, included a fully automatic hybrid mesh generator, which incorporated cut-cell Cartesian meshing of the far-field, and a near-field mesh extruded from an unstructured quad-dominant surface mesh. He spent many years working on the advancing layer mesh generation module, as well as developing a mesh deformation capability for these hybrid meshes. He also gained experience in the advancing-front mesh generation technique used for the surface meshing, as well as the refined Cartesian meshing employed in the far-field.
In 2004, ARA worked closely with the German Research Establishment, DLR, to provide a hybrid CFD tool-chain which combined SOLAR mesh generation functionality with the TAU flow solver. This required significant changes to the mesh generation capability in SOLAR and he worked on developing methods to integrate the advancing-layer near-field mesh with a tetrahedral far-field mesh in a conformal manner. This project brought him into closer contact with the Delaunay technique and other aspects of unstructured mesh generation.
In 2011, he moved to ICON Process and Technology Consulting Ltd, and is now developing the meshing capability within the ICON FOAMpro CFD suite. This means working with much more complex geometries, using fully parallel refined octree meshing and layer extrusion.
After graduating with a BS degree in Aerospace Engineering in 1986, I joined Atlantic Research Corporation as a structural analyst on solid fuel rockets and solid fuel gas generator systems. My main focus as a structural analyst was generating meshes and solving finite element models using tools from DOD funded labs and university research. I also used commercial products including PATRAN and MSC Nastran, and SDRC Ideas. At this time 3D modeling was becoming accepted as a standard design tool even though 3D meshes and solid finite element models were more common on the analysis side. During my 10 years at Atlantic Research Corporation, my more notable assignments involved metal matrix composites, RSRM redesign proposal with NASTRAN superelements, graphite epoxy rocket motor cases, viscoelastic solid fuel propellant material models, and rocket nozzle design and structural/thermal analysis. I began writing software to help generate special boundary conditions and set up composite material properties as well as post processing stress, strain and displacement results. At the time there were not many integrated commercial software products to set up material properties for filament wound composite pressure vessels for detailed structural analysis or applying an isentropic pressure distribution on a rocket nozzle exit cone. My development of custom in-house software led to a career change from an Aerospace/Structural Engineer to a Software Engineer working for a CAD/CAM/CAE company. I started my new career at Structural Dynamics Research Corporations in 1996. After a few years writing code, which was probably the most fun I ever had, I was promoted to the development manager of the meshing team for the SDRC Ideas Simulation product. In my 14 years as the leader of the meshing team, I have learned much more about meshing theory and areas of research then I was aware of as a structural analyst. SDRC was merged with UGS, eventually purchased by Siemens, and renamed to Siemens PLM. During this time, the product evolved from IDEAS CAE to NX simulation. I am now in the 26th year of my career, all as some type of Engineer. My current software development team also does virtual geometry and geometry prep for NX Simulation in addition to mesh generation. My first experience with the IMR was shortly after I joined SDRC in 1997 when the IMR was held in Dearborn, MI. It was a good experience and members of the development team have attended most of the IMRs since that time and submitted multiple posters and papers.
Dr. Timothy Tautges is a Computational Scientist in the Mathematics and Computer Science division at Argonne National Laboratory. He also holds an appointment as Adjunct Professor in Engineering Physics at the University of Wisconsin-Madison. Dr. Tautges's research intersts include unstructured hexahedral mesh generation and component-based application of mesh and geometry in scientific comuting applications. He is responsible for the developmjent and open-source releases of the Common Geometry Module (CGM) and a Mesh-Oriented datABase (MOAB). He also is the Argonne Principle Investigator on the SciDAC ITAPS project.
Dr. Kees is a research hydraulic engineer in the Coastal and Hydraulics Laboratory of the US Army Engineer Research and Development Center in Vicksburg, MS. He received a PhD in Environmental Sciences and Engineering from the University of North Carolina at Chapel Hill in 2001. He then held a postdoctoral research appointment at the Center for Research in Scientific Computation in the Department of Mathematics at North Carolina State University until 2005 when he began work at the Coastal and Hydraulics Laboratory. His research interests include mathematical modeling of multiphase fluid and solid mechanics, computational methods for partial differential equations, and high performance scientific computing. Dr. Kees is a primary author of several high performance computing packages including the Proteus toolkit for computational methods and simulation and the Differential-Algebraic Equation ToolKit.
