Hierarchical Multiscale Modeling Method for Head/Disk Interface

Abstract

Multiscale modeling opens a new paradigm by providing a novel methodology of establishing molecular design criteria and potentially gives several orders of magnitude advances in nanotechnology. The head/disk interface (HDI) in the hard disk drive system investigated here can be used as a benchmark for multiscale modeling. Our approach, stemmed from the novel middle-out approach in modern multiscale modeling using the lattice Boltzmann method (LBM) as the centerpiece formulation, marches towards continuum level (top) and molecular level (bottom). This approach will become an extremely valuable tool in generating design criteria of HDI.
