AUTOMATIC GRID GENERATION AND FLOW SOLUTION FOR COMPLEX GEOMETRIES

The development of a new method for the automatic generation of comput ational grids around complex aerodynamic configurations is described. The grid-generation procedure uses a Cartesian cell, embedded, unstruc tured approach that enables the efficient placement of computational c ells to resolve important Bow regions close to the surface. The main d ifference between the present method and most existing grid-generation techniques is the avoidance of the need to explicitly generate a surf ace grid, This new approach is easily automated and is capable of prod ucing grids around arbitrarily complex geometries. The capabilities of the method are demonstrated with a selection of inviscid transonic fl ows solutions.
