Interactive Grid Generation on Small Computers.

Abstract

Progress has been made in both algebraic and elliptic grid generation. (1) The control point form (CPF) of algebraic grid generation has been improved in two aspects. First, new blending functions are developed which allow a computer software user to specify the locations of control surfaces arbitrarily. Second, a new implementation scheme is used in the CPF to recapture the clustering feature of given grids. (2) An effective technique of curvature control in elliptic grid generation has been developed and implemented to control the grid point distribution along curved boundaries.
