New Concepts for Multi-Block Grid Generation for Flow Domains Around Complex Aerodynamic Configurations.

摘要

A multi-block grid generation procedure is described in the report that is suitable for the construction of multi-block grids for numerical simulations of flows around complex aerodynamic configurations. The major new concepts are: topology and geometry of block decomposition specified first by an interactive domain modeller; the use of compound edges and faces; grid embedding; grid lines only C degree-continuous over block faces; and the use of a biharmonic solver for grid generation in faces.
