The purpose of this paper is to report that a weighted upstream ticheme for the gaslubricatedReynolds equation is stable and highly precise for a wide range of bearingnumber A. The following two methods for calculating the weight of the upstream arepresented: (1) the exponential method-the weight is given by analytical integrationsof a one-dimensional Reynolds equation, and (2) the stabilization method--the weightis given by the condition under which the one-dimensional discretized equation for nodepressure is stable. The optimum weights for infinitely long-stepped slider bearing areinvestigated and are certified that the optimum weight for a one-dimensional case is theoptimum weight for a two-dimensional case too. It has been clarified that the stabilizationmethod is more precise and economical than the exponential method.
