Journal reference: Comput. Phys. Commun. 196(2015)429
Programming language: Python input scripts and a C core.
Computer: Desktop.
Operating system: UNIX.
RAM: 500 Megabytes
Keywords: NC-AFM, SPM, Simulation, Python.
PACS: 68.37.Ef, 68.37.Ps, 61.50.Ah.
Classification: 16.4.

External routines: GCC, Python 2.7, scipy and numpy

Nature of problem:
Simulation of any atomic force microscope operational mode including experimental delays/artefacts.

Solution method:
A modular simulation was developed where a user can connect several components together in order to simulate any operational mode. Each of these components are also developed to be mathematically similar to their real life counter parts hence incorporating any experimental delays or artefacts.

Restrictions:
The tip-sample interactions must be calculated before the AFM simulation.

Unusual features:
Modularity

Additional comments:
In order to obtain the tip-sample interactions a separate DFT or MD calculation must be performed.

Running time:
2 hours. The example given in the installation section of the user manual only takes about 30 seconds.
