Self-adaptive-grid method devised and enhanced for efficient computation of complicated three-dimensional flows. Extension of method developed for two-dimensional flows. Fictitious springs connecting points of computational grid used to determine optimum grid spacing. Each point connected to neighboring points by tension and torsion springs. Stiffnesses of tension springs related to flow-field quantities. Stiffnesses of torsion springs resist departure of grid from orthogonality.
