We have made freely available several online simulation tools via the nanoHUB. Check them out!
-
The Atomic Stick-Slip Toolkit enables you to easily perform non-equilibrium molecular dynamics simulations of the atomic stick-slip that occurs between an atomic force microscope tip and substrate, and then analyze their simulation results quantitatively.
-
The Forced Protein Unfolding simulation tool allow you to easily perform non-equilibrium molecular dynamics simulations of a protein subject to an external force and then analyze their simulation results both quantitatively and through animations of the protein dynamics.
-
The Protein Contact Maps tool lets you quickly and easily generate contact maps and distance maps for protein molecules. Input may be given in one of two ways: If an RCSB Protein Data Bank identifier is given, the tool will automatically retrieve the structure from www.pdb.org. The user may also upload their own .pdb file. If a file is given which contains multiple models representing a trajectory, then the results will be shown as a sequence of plots.
-
The Frenkel-Kontarova Model tool lets you simulate the movement of simple liquid molecules over a 2D potential energy landscape due to external forcing using the Frenkel-Kontarova model. Users can specify the molecule, surface and forcing conditions, and then analyze the predicted molecular movement, energetics, and slip behavior of the system.

The Atomic Stick-Slip Toolkit enables you to easily perform non-equilibrium molecular dynamics simulations of the atomic stick-slip that occurs between an atomic force microscope tip and substrate, and then analyze their simulation results quantitatively.
