Abstract

The unstructured triangular mesh, together with the finite volume method, the multi-grid technology and the pressure adaptation scheme as well as the probability model and the 9D model, is employed to study the static and dynamic flying characteristics of a slider with complex rail shape. Good numerical convergence is observed based on the algorithms, which makes the simulations of deep head/disk contact state possible. The unload performances of the slider with hook limiter is studied. It is believed that the unstructured triangular mesh and its related algorithms are good at simulating the nanometer-spaced air bearing slider with complex shape.
