This volume contains 14 papers, presented at the Symposium on High Performance Scientific Computing organized by FORTWIHR, the Bavarian consortium for HPSC, and held on June 17-18, 1993 in Munich, Germany. The numerical simulation, for example, the mathematical calculation of technical processes in advance, has gained immensely in significance for numerous key areas of the economy. It is now possible to understand and master entire technical processes before going into production by means of numerical simulation on the computer. The papers of this volume give a survey on recent research efforts and industrial applications of numerical simulation in the areas of fluid mechanics, dynamic systems in aerospace, melting processes and crystal growth, and semin-conductor and electric circuit technology.
