A preprocessor for numerical grid generation of boundaryfitted grids  An application to a solid propellant ablating boundary problem
Abstract
A code is described which demonstrates the versatility of the differential equations method of grid generation for generating boundaryfitted grids. Two problems from the field of solid mechanics are used to show the code's utility. The problem of successively generating grids for a geometry which changes with time is illustrated with the case of an ablating solid rocket propellant grain. On a more quantitative basis, the problem of successively generating grids whose grid points automatically position or 'adapt' themselves in order to resolve gradients of interest in an evolving solution is illustrated with the classic case of analyzing the state of stress in an axially loaded, rectangular plate with a centered circular hole.
