For a hard disk device (HDD) in operational state, there is an air bearing film between its head slider(s) and its disk(s) in the head-disk interface (HDI). Generalized Reynolds equation can be used to describe the pressure distribution of the air bearing film. Meshless local Petrov-Galerkin (MLPG) method was proven to be an efficacious method. No meshes are needed in MLPG method either for interpolation of the trial and test functions, or for the integration of the weak form of the related differential equation. It is a truely meshless method. The MLPG method is employed to investigate the pressure distribution...
