• A new FEM/FDM composite scheme is presented for two-dimensional incom-pressible flow problems combining the finite element method, which is best suited to analyze flow in any arbitrarily shaped flow geometry, with the finite difference method, which is advantageous in both computing time and computer storage. The combination of both methods enables large-scale viscous flow to be analyzed, which is crucial for both the detailed analysis of three-dimensional flows and the solving of problems of flow around moving bodies. A modified ABMAC method is used as the basic algorithm, to which a sophisticated time integration scheme proposed by the present authors has been applied. Numerical results including moving boundary problems indicate good agreement with experimental results.
