Abstract:

A summary of the technical work performed during the past twelve months under AFOSR Grant 85-0195 is presented in this report. Significant progress on a number of adaptive concepts has been made. Problems associated with earlier adaptive mesh schemes controlling cell areavolume have been resolved. Resolution of this difficulty led to the evolution of an adaptive orthogonal scheme for two-dimensional grids. This technique is even structurally simpler than the original Poisson equation based adaptive methods. Other research emphasis has been placed on developing an unstructured solution scheme as a fast solver to generate these grids.
