Adaptive Grid Generation Using Elliptic Generating Equations with Precise Coordinate Controls.

Abstract

The investigators are in the final stages of developing a toolkit of symbol manipulation codes for variational grid generation. They will present an invited paper on this work at an AIAA Aerospace Sciences Meeting. They have also discovered an unexpected folding of the grid for a design case using a popular grid generation code. A paper analyzing the problem was presented at the AIAA Computational Fluid Dynamics Meeting in July. The analysis has suggested practical values of relative weighting parameters for use in variational grid generation techniques. A paper has been submitted to the journal Applied Mathematics and Computation. Additional keywords: grids(coordinates); adaptive systems. (Author)
