Seminar - Grid Generation (WS 2007/08)


Contact person:
Dr. Michael Bader

Classification:

Time and Place:

Preliminary session (Vorbesprechung) on Monday, Oct 22, 2007 (14:00) in room 02.05.033. The seminar session will be two block sessions on Dec 6 and Dec 8 (see schedule below).

Seminar Topics:

A quite common approach to represent continuous data in 2D, 3D, or even higher-dimensional domains is to approximate or interpolate this data on an appropriately generated computational grid. Applications exist in many fields of computational sciences; typical examples are finite difference or finite element methods in numerical simulation, the representation of geometrical objects in computer graphics or visualisation, and even general classification problems in data mining.

Algorithms and methods for grid generation are at least as diverse as their applications. It is the aim of this seminar to discuss several common approaches, for example:

Seminar Outline:

The talks (approx. 45 minutes) in the seminar will be given in English. In addition to her or his talk, each student will have to prepare a short paper (8-10 pages), which will be reviewed by two other seminar participants. The paper and the two reviews will, in addition to the talk, be considered to determine the final grade.
