Operation movies for MD

"Molecular Dynamics AFM Image Simulator" calculates the tip-sample interaction and considers the deformation of the molecule. It monitors the time evolution of a molecular conformation by calculating the Newton's equation of motion.

Force curve measurement mode
We derive the forces to the tip which comes up to the sample at a specified position on the sample surface.
Constant-height mode
We derive the forces to the tip which scans on the sample surface at a constant height.
Non-contact mode height constant
We derive the forces to the tip which scans on the sample surface while oscillating around a constant height. As a result, we obtain a frequency shift image and an energy dissipation image.
Relaxation
We calculate the structural relaxation of a sample molecule as a preparation for a simulation.
