Front method is an efficient method for calculating large coupled linear equations of 3-D FEM. But, to our best knowledge, a complete software package for applying front method to 3-D FEM simulation is still unavailable. We developed such a software package in FORTRAN. Figure 3 shows the schematic diagram of solving coupled linear equations by front method. The software has been used in 3-D FEM numerical simulation of the precision forging process of a blade with a damper platform. Comparisons are made with Gauss method, and the results are given in Table 2. They show that front method is much better than Gauss method in solving larger-scale coupled linear equations. Applications show that our software is suitable for high precision and efficient 3-D FEM simulation of large-scale plastic forming processes.
