HEMP advection model
The automatic rezoning procedure now being developed for a version of the HEMP code is outlined. HEMP is a two-dimensional, Lagrangian, fluid dynamics code with slide lines and elastic--plastic material strength models. The rezoning procedure is adapted directly from the OOZE code. Cylindrical symmetry is considered. By omission of appropriate radial factors, everything is applicable to plane symmetry. Since the procedure is equivalent to a finite difference solution of the advection term in the generalized fluid dynamics equations, it is often referred to as advection. First, an outline is given of some general physics considerations for the rezoning problem. Next, several changes in the OOZE algorithm are specified. Then a detailed outline of the algorithm developed for HEMP is provided. 7 figures. (RWR)
