NUMERICAL GROUND MOTION STUDIES. VOLUME I. STUDY OF NUMERICAL SOLUTION ERRORS IN ONE- AND TWO-DIMENSIONAL FINITE DIFFERENCE CALCULATIONS OF GROUND MOTION.
Abstract
Results are presented of a study to determine numerical solution errors in two-dimensional hydrodynamic calculations of surface bursts. The changes in solution errors due to variations in mesh point distribution are studied in one and two dimensions; the results of the investigation are applied to improving the solution to a two-dimensional problem. A method is described which allows a grid to expand automatically to contain a moving shock. Methods are presented for achieving several kinds of mesh point distributions based on a geometric progression in the distance between mesh points. (Author)
