SPM Simulator : question for solver selection page(011)

We introduce solvers appropriate for AFM simulation on the micrometre scale.
There are three choices, GeoAFM, FemAFM, and LiqAFM.
Click a word "GeoAFM", "FemAFM", "LiqAFM" in each light blue box, and you can jump to the web page explaining about the feature of the solver.

There are three choices of solvers for your purpose.

GeoAFM	Geometrical Mutual AFM Simulator	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.
FemAFM	Elastic Body AFM Simulator	An AFM image of a soft material or a force curve of it is predicted. AFM is simulated with an approximation of a tip and a sample by the model of continuout elastic medium. Deformation of a tip and a sample is reproduced by solving elastic equations numerically under the assumption that the tip and the sample are continuous elastic mediums of a single material respectively and Van der Waals force interacts between them. It is also possible to simulate contact between a tip and a sample with viscoelasticity and to calculate a force curve.
LiqAFM	Soft Material Liquid AFM Simulator	AFM experiment under the liquid environment is simulated. It is possible to reproduce vibration of a cantilever in liquid and to calculate resonance frequency. It is also possible to simulate contact between a tip and a sample with viscoelasticity and to calculate a force curve.

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