Objective:
Developing a CAE tool by which analyses are implemented directly on the CAD model of an engineering product rather than an elaborately built discretized mode, which is different from the real product geometrically and topologically. We call these analyses Complete Solid Stress Analysis (CSSA). To achieve this goal, we have proposed the Boundary Face Method (BFM), which is an efficient solution method to the Boundary Integral Equation (BIE) and makes direct use of the B-rep data of a solid that available in all CAD packages. This tool has the following characteristics:

• Automatic meshing and analysis for complicated structures with complex geometries
• Accuracy much better than existing FEM tools, to ten digits or more, is achievable and able to capture local stress concentration at any small sized features of a structure
• Arbitrary geometries and material compositions of structures can be easily handled by seamless interaction with CAD packages
• Accelerated by the fast methods, such as the Fast Multipole Method, the Hierarchical Matrix and the Adaptive Cross Approximation, thus able to perform large-scale computation within due time
• Adaptive solution procedures to guarantee the reliability of the computational results
