Automatic grid generation and flow solution for complex geometries

Abstract

The development of a new method for the automatic generation of computational grids around complex aerodynamic configurations is described. The grid-generation procedure uses a Cartesian cell, embedded, unstructured approach that enables the efficient placement of computational cells to resolve important flow regions close to the surface. The main difference between the present method and most existing grid-generation techniques is the avoidance of the need to explicitly generate a surface grid. This new approach is easily automated and is capable of producing grids around arbitrarily complex geometries. The capabilities of the method are demonstrated with a selection of inviscid transonic f..
