Mainly based on mixed-language programming with Fortran and Visual Basic,a method used for developing the specific FEM code with friendly user interfaces and high computation efficiency is proposed.

Visualization technologies of structural fatigue life and reliability such as finite element software with large scaled graphical user interface, prediction model of fatigue life, realization method on visualization of fatigue life and reliability and so on are introduced.

On the basis of maintaining the basic characteristics of original class,this programmer can strengthen and reduce the function of the class by means of the inheritance and polymorphism, thereby realize the expansion of the finite element software .

Study and realization of seamless link between FEM software and universal graphics software;

There is perfect function of partition in many FEM software, but the chart editing of them can not meet the demand of users.

Application of ANSYS finite element analysis software to locomotive main alternator electromagnetic field analysis;

The stress-strain contour of the plate in hardening process was simulation analyzed by finite element analysis software, the result of the analysis was consistent with the actual.

Based on finite element analysis software ——ANSYS, the casting riser and running system CAD software for simulating casting forming process is developed by using ANSYS' inner developing tools (APDL and UIDL) and outer developing tools (Visual C++).
