 Abstract

The technical concepts of a method for the generation of 3D block-structured grids are presented. The generation process is decomposed in four more or less sequential steps. 1. Topological block decomposition. 2. Geometrical modeling of known and unknown coordinate functions. 3. Grid initialisation by multi-linear transfinite interpolation. 4. Elliptic cell partitioning. The elliptic method is based on simple partial differential equations representing locally decoupled ID stretchings followed by 3D rotations. Mesh-size and smoothness control occurs with user-provided weight functions that are inversely proportional to desired mesh sizes. Test results are shown.
