A comprehensive set of programs have been developed for analysis of complex two- and three-dimensional geometries in the Mechanical Engineering Department of the University of California's Lawrence Livermore Laboratory. State of the art finite element and hydrodynamic codes are being used for the analytical portion of the work. To assist the analytical effort, several additional codes which depend heavily on graphics have been developed. These are basically used for the pre- and post-processing of the data. Prior to running any analysis, the geometry of the body of interest must be represented in the form of small “finite elements”. After the analysis is run, the data must be post-processed. Both spatial and temporal data exist in the database. It is the database between the analysis codes and the post-processors which allows a wide variety of analysis codes to use the same post-processors.
