| Description | Dynamic Approach Curves is the premier tool of a suite of tools being developed under the title of VEDA - Virtual Environment for Dynamic AFM. This tool accurately simulates the oscillations and tip-sample interaction forces of an AFM cantilever probe excited near resonance and brought close to a sample in either ambient conditions or ultra high vacuum. This tool features (a) accurate models of AFM probe dynamics, (b) realistic tip-sample interaction force models and (c) accurate, FORTRAN based, numerical integration schemes that are well-suited for non-smooth, nonlinear differential equations. From the tip oscillation time histories, which are simulated with a relative tolerance of 1e-9, quantities such as amplitude and phase of the first harmonic, peak interaction force, mean interaction force, and power dissipation are calculated. For detailed information about this tool, please consult the User's Guide. |
