• Head disk interface
• lattice Boltzmann method
• molecular dynamics
• multiscale modeling

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