A general three-dimensional elliptic grid generation system on a composite block structure

Abstract A general three-dimensional elliptic grid generation system is discussed. This system includes automatic evaluation of control functions from an algebraic grid or interpolated from boundary point distributions. Also included is iterative adjustment of control functions for boundary orthogonality. The solution is by point SOR iteration using a field of optimum acceleration parameters. This system is incorporated in a code that can treat any physical configuration by using a multiblock structure with complete continuity across interfaces.
