Two-Dimensional Mesh Adjustment Algorithm.

Abstract

Mesh adjustment by the use of solution-dependent monitor functions that take equally spaced values at mesh nodes has been studied mainly by means of examples. The simplest effective monitor is distance along the solution curve or surface. This monitor provides the desired concentration of nodes where the solution has large variation. A monitor depending on both distance and curvature can be much more effective. A 'best' monitor that minimizes the truncation error of the difference method of numerical solution has been found and used as a standard of comparison. Application of the monitors to reactive flows or flows over an airfoil has been impeded by as yet unexplained technical difficulties. (Author)
