Abstract

Summary The project 11172 is embedded in the Collaborative Research Center 381’Charakterisierung des Schädigungsverlaufes in Faserverbundwerkstoffen mittels zerstörungsfreier Prüfung’ (SFB 381). The SFB 381 consists of theoretical and experimental groups in Stuttgart and one theoretical group in Karlsruhe. With help of the CrayT3E we perform large-scale numerical solutions of the elastodynamic wave equation in 2-D and 3-D. These solutions are required to get a better understanding of complex wave phenomena and hence to develop new non-destructive testing methods. Our work on the CrayT3E is based on the program Ultimod [1,4]. The parallel HPF-implementation has been done in the Cray-projects PARSEP and ERDMOD in Stuttgart described in [2,3]. In one part of our project we have modified this program in order to solve our specific problems. This is described in the article ’Modeling of elastic waves in fractured media’ in this report. The other three articles are related to SFB 381 topics that are in connection with our Cray-project and rely very much on synthetic data generated within this project. The resource requirements of our program strongly depend on the given problem (model-size, timesteps to calculate, …). Until now, we restrict ourselves to relatively small jobs (N64med-queue), but with our new approach — high contrast 3D-FD-modeling — we are going to calculate very large-scale problems.
