COUPLING OPENFOAM WITH FENICS FOR MULTIPHYSIS SIMULATION
There is a trend of tight integration of Computer-aided Design(CAD) and Computer-aided Engineering(CAE) for both commercial and open source software packages.CAD platforms not only create geometry,but also provide functions of computational engineering and product life management.Meanwhile,CAE software for physical system simulation,has strengthened the geometry creation and meshing capability for a smoother engineering process.However,there are gaps for an automated engineering design/optimisation process from geometry prototyping to Computer-aided Manufacturing(CAM).In particular,the changed geometry topology,i.e.the way surfaces forming a solid geometry,will invalidate meshing and boundary condition setup in CAE,because the boundary setting is linked with volatile surface identifier integer,not the spatial coordinates.This suggests understanding geometry topology is the key to optimisation and simulation automation.
