We have developed an interactive \u00a0dynamic AFM simulator (dForce<\/strong>) which is based on the experience and knowledge accumulated in Garcia\u2019s group over 20 years of\u00a0 simulations.\u00a0 The code is valid for air or liquid environments, soft or hard materials, small or large amplitudes, conservative and non-conservative forces and single or bimodal excitation modes. Its accuracy has been tested against previous numerical simulations. The dForce simulator will be useful to either devise the optimum experimental conditions in terms of amplitudes, peak forces, material properties sensitivity\u00a0 and spatial resolution or to explain the experimental data in standard and non-standard dynamic AFM configurations. The code is open-source; it is compatible with Linux and windows operative systems and it can be freely downloaded from our web page.<\/p>\n
