A computer program called PREMSAP to prepare input data for structural analysis and design of structures (including car frames and parts), along with a program called MSAPLOT to display graphically the mathematical models, have been developed for the University of Michigan Structural Analysis Program MSAP. The latter is based on SAP IV and has the same input format.
PREMSAP is a format free interactive program with quadrilateral and linear, nodal point and element mesh generation options for preparing the input data for MSAP for static and dynamic loads.
Using the PREMSAP output, or otherwise prepared MSAP data, MSAPLOT plots line, plane and 3-D objects in isometric, perspective and hidden line forms. It also allows the user of MSAP to view the deformed structure due to static loads or dynamic mode analyses, produce ink drawings through the CalComp plotter, and draw stress contours for membrane and eight-node brick elements.
Use of PREMSAP and MSAPLOT programs has been proved very successful by consultants, researchers, and students alike.
