- The principle of the predigestion in geometry modeling is omitting the function part and the non-load-carrying process structure, and to the big and transition arc, the curve is replaced by straight line using the thought of curve and free-surface segmentation . the physical characteristic of the digital model reflect on remaining the main mechanical characteristic of the objects . the shell element model is used in strength analysis, stiffness analysis and dynamic analysis
