![]() The program produces the bulk of the input data for SAPIV, which includes the nodal point coordinate card images and the element numbering card images. SPREP can be readily modified by the user to include additional features that are desired. ![]() The Type 8 elements can be generated for the following geometrical cases: a plate, a cylindrical shell section, a spherical shell section, or a toroidal shell section. Two types of element generation are available in SPREP: quadrilateral elements for two-dimensional plane or axisymetric problems (Type 4), and 8- more » or 12-mode three-dimensional elements (Type 8). The mesh description generated by QMESH can be transformed into appropriate card images for input to SAPIV by means of the preprocessor, SPREP. ![]() The development of a self-organizing quadrilateral mesh generator such as QMESH has made it possible to reduce significantly the amount of manual data preparation for SAPIV. = ,Ī finite element structural analysis program such as SAPIV can require a large amount of effort in data preparation, particularly for three-dimensional structural models and two-dimensional cases of complicated geometry.
