In this paper, we examined the accuracy and efficiency of the time marching scheme for the nonlinear-unsteady-direct analysis of coupled differential equations of the motion equation and the Reynolds equation. Examination of some schemes gave the following results : accuracy is influenced by the method of time marching and the coupling of the motion equation and Reynolds equation ; the scheme of integrating coupled differential equation by Runge-Kutta method is most accurate ; the stable scheme for spatial difference improves the accuracy of time integration. The method wherein a time marching step is controlled automatically improves the efficiency of calculation.
