Abstract:

As the trend continues towards exploiting the capabilities of the current generation
of super computers to model complex, three-dimensional flow fields, there is need
for advances in geometry modeling and grid generation technology to keep pace with
advances in Navier-Stokes algorithms. The proposed Computer Aided Grid Design (CAGD)
package is a step in that direction. The CAGD package will be developed on a scientific
workstation by coupling a CAD graphics system and the existing grid generation codes
with appropriate strategies. CAGD will offer a fast, efficient, and economical approach
to geometrical preparation. It will allow upgrading of the basic geometry in a step-by-step
fashion interactively and under permanent visual control. It will minimize the differences
between actual hardware surface descriptions and corresponding numerical analog.
Along with geometry-grid definition for a typical CFD application, CAGD will also
offer automatic boundary condition set-up for selected widely used Navier-Stokes
algorithms utilized in internal flow configurations.
