A software strategy towards putting domain decomposition at the centre of a mesh-based simulation process

Abstract

In the mesh-based computer aided engineering sphere the most man-power intensive stages in the simulation process chain are the model creation and mesh generation. Together, they can account for 60 to 90 per cent of the total modelling time for complex industrial 3D models. In component meshing and gluing (CMG) we take a novel approach, using domain decomposition technology, to try to reduce the total modelling time further within the existing process wilhoul incurring significanl re-engineering costs. The thinking is to off-load a sizeable portion of the workload performed by manpower in the creation and meshing stages to the downstream stage, the analysis, performed by computing horsepower. In this paper we describe the concept and software strategy for such an approach. © Springer-Verlag 2002.
