The biconjugate-gradient method is applied to the finite element analyses of the Navier-Stokes equations. The minimum storage requirement is realized by use of the hybrid mesh which is com-posed of the usual irregular elements and the regular elements. since the matrices emanating from the regular meshes have a regular structure and need not be stored entirely. The convergence of the iterative procedures is accelerated by the multi-level meshes which consist of several meshes of different mesh size. The flow in a driven cavity and the channel flow past a valve are computed to show the practicability of the proposed methology.
