| Abstract: | AutoCAD is taken as the geometrical platform while the secondary development technology that it offers is used to realize the finite element pre-processing system programming.The method solves the detachment of the geometric modeling system from the pre-processing system within the conventional finite element analysis system.Several other modules such as modeling,cell property setting,grid splitting and display are integrated.Several vital technologies in the finite element pre-processing system are studied,including the way to control a grid pattern,output of solution data interface,ObjectARX-based CAD/CAE integrated design,and complex three-dimensional solid tetrahedral grid automatic generation algorithm.Based on AutoCAD,a finite element pre-processing system is established. |
