The Coupling Approach of Boundary and Finite Element Methods to Incompressible Viscous Flow Problems
A coupling approach of the boundary element method and the finite element method for the incompressible viscous flow problems is presented. A domain involving an obstacle is divided into two subdomains. The subdomain involving an obstacle is assumed as an incompressible viscous flow, and the finite element method is applied to simulate the flow. The other is assumed to be a potential flow, and the boundary element method is applied to the flow field. Numerical results of the flow past a step demonstrate the applicability and effectiveness of our approach.
