Adaptation of Structured Grids Based on Weighted Least Squares Formulations

摘要

The thesis deals with adaptation of so-called single-block structured grids witha fixed number of grid points, as a tool to provide automatic control over the distribution of these grid points. In the first part, the so-called Equidistribution Principle is introduced which forms the basis for the grid adaptation techniques developed. After a brief discussion on grid quality the literature is reviewed on existing techniques and the thesis objectives are formulated. The second part contains the theoretical background. The third part
