We explain features of Geometrical Mutual AFM Simulator GeoAFM in this page.
Click the following word "GeoAFM" and you can jump to the web page explaining about calculation modes of the GeoAFM solver.

The features are ... We can guess one of the three data, 3-dimensional shape data of a tip, shape data of a sample surface, and measured AFM image data, from two others at very high speed. Each data is mutually predicted by purely geometrical calculation on the system. So interactions such as Van der Waals force between a tip and a sample or deformation of the tip and that of the sample is not taken into account. Polymers, soft matters, organic compounds, metals, semiconductors, and inorganic compounds can be used as a sample.

	measured AFM image data
shape data of a sample surface		3-dimensional shape data of a tip

Data representing a structure of a sample is needed on the simulations above.
Structure data of various proteins is provided by Protein Data Bank http://www.rcsb.org/pdb/home/home.do as files of the PDB form.
It is possible to simulate easily with files of them.

If you can't find a simulation for your purpose or can't understand how to prepare structure data for a sample, mail us by clicking the illustration below.
A symbol of a position where trouble occurs will be inserted into the subject of the mail.
