The formulation of a general numerical method for fluid film lubrication of irregular bearing shapes in the high bearing number region is presented. We expand the formulation of the divergence formulation method to the triangular element used in the finite element method. Here, the pressure function is not an element-interpolation function but a node interpolation function. The mass flux is evaluated along the sides of the triangular elements, so that several calculation schemes, which are commonly used in the divergence formulation method on structured grid systems, can be introduced for unstructured grid systems easily. The formulation is suitable not only for acute-angled triangular elements but also for obtuse-angled triangular elements. Numerical examples demonstrate the applicability and accuracy of the method.
