Object-oriented modelling, analysis and concurrency in the boundary element method K.H. Lee, K.W. Tan Department of Mechanical and Production Engineering, National University of Singapore, 10 Kent Ridge Crescent, 0511 Singapore ABSTRACT The object-oriented modelling environment described in an earlier paper is adopted for the implementation of the boundary element method in two- dimensional linear elastostatics analysis. In this environment, object representation is facilitated with the use of three different application classes, namely, the geometry, the mesh and the system of equations. Object communication is made through communication channels and messages. A database management system is employed for the matrices in the system of equations in order to provide a good referencing system for equation coefficients belonging to entities in the geometry and mesh classes. The object representation thus allows the integration of the modelling with the
