## Development of a Parallel Grid Generator with Integration of a Parallel
Flow Solver emphasising Load Balancing Aspects

Cooperation with DLR Köln.

This project seeks to develop a parallel grid generator
and to assemble a uniform, parallel environment - an integrated process
of development - for the construction of computational grids (meshes),
for the partitioning of meshes, and for the computations of simulations.
Currently, the grids are sequentially constructed and are simply
partitioned for the parallel flow solver. The quality of the meshes
are evaluated automatically by geometry criterions and by hand inspection.
The use of very large data sets needs a more practicable and automatic
method. The parallel grid generation combined with the flow
solver makes it possible to shorten the development cycles, to operate
on a larger dataset and to extend methods for controlling grid quality.

In a first step, a geometry partitioning will be developed.
This will serve as a basis for the parallel grid point generating. In a
second step, the flow solver will be integrated. All aspects of load balancing
will be handled here by the geometry partitioning. The parallel grid generator
for two and three dimensional problems will be tested and verified
on stator-rotor examples.
