Within a successful CAE driven product development,there are two fundamental issues: a seamless interaction between the CAD and CAE software tools and a fast solver for very large scale computation.The first issue is associated with the discretization of any complexly shaped domain into elements for a mesh-based method,such as the Finite Element Method(FEM)or Boundary Element Method(BEM).In the best case modifications in the CAD model can be transferred tithe CAE model and vice versa.The second issue is inevitable for a daily design process,as a complete simulation chain for practical problems usually involves very large scale computations and can be very long.
