摘要：

Subdivision surface modeling, which is based on polygon mesh modeling, can generate a whole smooth geometry without limiting to the topology and connectivity. Meanwhile, the boundary element analysis (BEA), which is based on the boundary integral equation, requires only boundary discretization of the body in question. Thus, performing BEA directly on the subdivision surface models may be a promising way to realize the seamless integration. This work presents a unified framework for the BEA and CAD modeling based on the subdivision surface. Numerical examples for 3D potential problems have demonstrated that the implementation is successful.
