A 3-D FEM/FDM overlapping scheme for viscous, incompressible flow prob
lems is presented that combines the finite element method, which is be
st suited to analyze flow in any arbitrarily shaped flow geometry, wit
h the finite difference method, which is advantageous in both computin
g time and computer storage. The combination of both methods enables l
arge-scale viscous flow to be analyzed, which is crucial both for deta
iled analysis of 3-D flows and for solving flow problems around moving
bodies. A modified ABMAC method is used as the basic algorithm, to wh
ich a sophisticated time integration scheme, proposed by the present a
uthors, has been applied. In this paper, some numerical results includ
ing 3-D heat and mass transfer problem and moving-boundary problems ar
e presented.
