GRID and CQUAD, Two Preprocessing Codes for NASTRAN

Abstract

Two preprocessing codes were designed to generate a grid and CQUAD2 elements for rectangular plate problems to be analyzed by NASTRAN. The GRID program generates a two- or three-dimensional grid with uniform spacing as specified by the user, i.e., A, B, C is the uniform spacing in the X, Y, Z directions, respectively. Any leftover uneven increment is placed in the last interval. CQUAD generates CQUAD2 elements to fill the two-dimensional grids generated by GRID. Both programs punch out the appropriate cards needed for input.
