Abstract: The finite element method to solve the Navier-Stokes equation is generalized to combine with a molecular model, the multibead rod, so that the flow problems of rigid rodlike suspensions can be simulated properly.The solutions of flow fields and the most probable orientations of multibead rods have been obtained for several steady flow problems and both shown in figures of this paper. The interesting results prove the treatment of this method reasonable.The finite element method to solve the Navier-Stokes eq...
