Short Courses


The IMR short courses will be held Sunday, October 12, 2014. Courses are taught by internationally known experts in the field of Mesh Generation. Each course is an hour and a half in length including breaks. Instructors will address practical issues in the design and implementation of both structured and unstructured mesh generation codes.

These courses are ideal for students just entering the field who may need a foundation for research as well as any seasoned professionals who would like to expand their current skill set in the development of mesh and grid generation algorithms. To register for the short courses, mark the appropriate boxes on the registration form.

Instructor Bios and Course Abstracts

Dr. Steven J. Owen, Sandia National Laboratories

Title: Introduction to Quadrilateral and Hexahedral Mesh Generation

Biography: Steve Owen is currently a researcher and software developer at Sandia National Laboratories and has been a member of the CUBIT development team for the past 15 years. Hexahedral mesh generation and its related technologies have been the focus of his activities for the majority of his career. Steve graduated from Carnegie Mellon University in 1999 with a PhD in Civil Engineering and undergrad from Brigham Young University in 1992. Steve was awarded the IMR Fellow award at the 2013 IMR in Florida for his research accomplishments in meshing and contributions to the International Meshing Roundtable over the past two decades.

Abstract: This short course reviews the theory and application of quadrilateral and hexahedral mesh generation. We first define the use cases for hex meshing over traditional tetrahedral methods and why the general all-hex problem is fundamentally more difficult. Beginning with basic transfinite interpolation methods and exploring various advancing front and overlay grid approaches we will describe a wide range of all-hex methods currently in use today. We will also review mesh modification and improvement strategies for all-hex meshes including topology operations, smoothing, refinement and coarsening. More recent research strategies that utilize dual-based technologies, frame fields and parallel methods will also be discussed.

François Pellegrini

Title: Partitioning and Mapping Unstructured Meshes on Distributed Memory Architectures

Biography: François Pellegrini is a professor in informatics at Université de Bordeaux, and a researcher at LaBRI and at Inria Bordeaux. He has been investigating the problems of graph partitioning and static mapping for more than 20 years, by designing both sequential and parallel heuristics. He is the architect and main developer of the Scotch and PT-Scotch software. He is also at the inception of the PaMPA parallel library for distributed mesh handling, partitioning and remeshing.

Abstract: This course focuses on the use of partitioning and mapping tools for efficient parallel execution of unstructured mesh software.

We will discuss the following topics:
  • Current trends in parallel architectures
  • Desirable features for writers of numerical solvers based on unstructured meshes
  • The partitioning and static mapping problems
  • Classical algorithms to solve these problems
  • The graph representation of meshes
  • The hypergraph representation of meshes
  • Representing and using centralized graphs (e.g. in Scotch)
  • Representing and using distributed graphs (e.g. in PT-Scotch)
  • Representing and using distributed meshes (e.g. in PaMPA)

Mark Gammon, Product Manager, CADfix

Title: Practical Guide to Using Mesh and Geometry Frameworks in Advanced Computational Software

Biography: Since joining TranscenData 19 years ago as an application engineer Mark, has worked in most areas of CADfix software development, ranging from CAD translation to user interface and mesh generation. Mark is now the product manager for CADfix and leads the software development team.
