An Automatic Adaptive Rezone Scheme for HULL Code

Abstract

An adaptive rezoning algorithm has been developed and used in the Orlanda Technology, Inc., version of the HULL hydrocode. The algorithm is completely automated with the grid point locations based on values of the pressure and its derivatives. Sample computations of underwater explosions demonstrate how adaptive rezoning can be used to calculate more reasonable solutions without increasing the total number of grid points....
