Abstract:

Numerical grid generation is a critical link in the chain of events leading to numerical
solutions of partial differential equations of fluid mechanics. However, it is often
(if not always) very difficult to ascertain how "good" a given grid is, particularly
for three-dimensional configurations. This project is aimed at developing true, quantitative
measures of a "good" grid along with improvements in adaptive grid strategies. The
formulation of these measures will be based on the geometric characteristics of the
flow field region, the variations in solution behavior, and the numerical algorithm
under consideration. The method will offer an ability to select an "optimal" grid
associated with the application being addressed and will provide diagnostic tools
for grid systems.
