Abstract

Input preprocessors have come to be recognized as important components of modern finite element programs. A method is described which utilizes interactive computer graphics digitizing techniques to create a powerful input preprocessor for finite element analysis. A limited number of general mesh generators based on linear blending functions permit the program to handle virturally all two-dimensional topologies. The processes of geometric input and specification of problem-specific "attributes" have been kept separate so that the mesh generation routines may be used with a variety of analysis programs. Graphical editors have been implemented to specify attributes for structural mechanics problems. Although this type of graphical preprocessor shows considerable promise for applications in three dimensions, there are still unresolved problems in the areas of geometrical description, perception, and interactive hardware.
