Abstract Contact at very tiny length–scales is characterized by atomic force interaction. A technical application of interest is the atomic force microscope (AFM). A coupled molecular dynamics (MD) – finite element (FE) approach is outlined to tackle the multi–scale problem by numerical simulation. Guidelines for the spatial discretization are derived from convergence studies. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
