Parallel computing has become a key component of high performance computing in the 90’s. In order to exploit this technology in science and engineering, in particular for aerospace, automotive, and turbomachinery applications as well as in environmental simulation, highly complex geometries have to be dealt with, often generated by CAD systems. In order to bring CFD in the design loop, quick turnaround times are mandatory.

Grids are multiblock hexahedra allowing any kind of topology and comprise any number of blocks. Grid generation is completely non-interactive. Only a wireframe and the geometry description are provided. Surface and volume grids are generated together. Grids are slope continuous. Grids are constructed using a high-level grid generation language. Grids consist of objects that are reusable. A problem/user specific grid database may be constructed that allows to use more complex entities from which to generate new grids. Complex grids are built in an object oriented fashion.
