      Robert Schneiders

I was research assistant with W. Oberschelp at the Lehrstuhl für Angewandte Mathematik, insbesondere Informatik. My interests are in mesh generation, finite element methods, cfd, simulation of metal forming processes and multiscale techniques. I specialize on the generation of hexahedral element meshes, and I wrote my PhD thesis on this topic. I also do some consulting in the mesh generation field.

Listed below are examples of the research stuff I am currently working on.

  • An algorithm for the generation of hexahedral element meshes

  • New example meshes (octree-based, unstructured hexahedral)

  • Examples of meshes (grid-based) for various geometries

  • Simulation of the cold forging of a steel part (with Rolf Bünten, Institut für Bildsame Formgebung)

  • An interesting open problem

  • Octree-based generation of hexahedral element meshes
  • Together with Wolfgang Dahmen (IGPM) I participate in the SFB 1580 "Strömungsbeeinflussung und Strömungs-Struktur-Wechselwirkung an Tragflügeln", an interdisciplinary research project on CFD where we will do the grid generation job. We are looking for a Ph.D. student who wants to work with us, so if you are interested, please let me know (click here for a job description). Besides that we do some work on wavelets, a field where Wolfgang Dahmen is a well-known expert.

    I maintain a WWW-page with general information on mesh generation (people, books, conferences etc.). Another interesting web site is the Meshing Research Corner, a comprehensive database with literature on mesh generation, maintained by Steve Owen.

    Together with Eberhard Baensch and Jürgen Bey I organize a summerschool on data structures and grid generation (Harburger Sommerschulen on numerical software).

    I am also involved in a joint project with the LIWW (institute for hydrology) on numerical simulation of free surface flow where Reinhard Kowalski works on numerical methods and Irmgard Dittrich does the mesh generation job.

    I am associated member of the interdisciplinary Postgraduate College Informatics and Technology. I am a member of SIAM and a reader of IEEE Computational Science & Engineering.
