Adaptive Gridding in Two Dimensions for Optimal Accuracy and Efficiency.
Abstract
Very accurate one and two dimensional shock calculations were made using moving grids, mesh refinements, consistent derivative formation, and Riemann solvers for interaction shocks. All calculations were done explicitly with no artificial viscosity. Error free 2D shocks were propagated using a grid velocity found by a rotation into direction of the maximum gradient and subsequent translation on to a frame which appeared steady. Additional Keywords: Shock waves; Shock flow. (Author)
