We have performed atomic force microscopy (AFM) simulation to clarify the microscopic mechanism of the AFM using a coupling model of atomic and continuum model. Dynamics of the cantilever is described by the continuum model and the atomistic interaction between the probe and surface is calculated by the Molecular Dynamics (MD) method. In order to couple the two different systems, we use MD/continuum hybrid method developed by our group. In this paper, we propose a simple model for AFM, where the probe and surface are consisted of Lennard-Jones atoms and cantilever is one-dimensional spring. We show frequency shift of the cantilever and the energy transfer from the cantilever to the atom on the surface.
