Mesh generation is a basic part of computational fluid dynamcis (CFD). However, as it is one of the major bottlenecks of CFD application in industry, increasing attention has to be payed to the development of fast and user-friendly, good quality mesh generation systems.

In this paper, the fundamental elements of the Deutsche Airbus GmbH’s (DA) interactive mesh generation system INGRID are described. Current enhancements deal with airplane component construction, surface mesh generation, 3D topological considerations, basic 3D block mesh generation algorithms, block mesh implantation and mesh smoothing experiences. Special emphasis is layed on a local sub-block embedding technique which directly fits into the context of multigrid flow solving.

The flow field is determined with DA’s MELINA code, a cell vertex, multigrid, multi-block Euler solver which is based on central differences, artificial viscosity and explicit 5-stage Runge-Kutta time stepping. MELINA already has a considerable impact on the aerodynamic design of complex 3D flow problems at DA such as laminar glove design, integration of propulsion systems or simulation of flap track fairings on the wing.

The validation experiments for INGRID/MELINA with wing/body/pylon/engine/flaptrack fairing configurations have shown that the reliability of CFD results is very high even for that complicated geometries. This offers great chances for future developments of efficient, safe and environmentally clean airplanes.
