The SimTK web site will be down from 7am to noon Pacific time Dec 7, 2016 (Wed) for infrastructure updates.

OpenMM includes everything one needs to run modern molecular simulations. It is extremely flexible with its custom functions, is open-source, and has high performance, especially on recent GPUs.

OpenMM is a toolkit for molecular simulation. It can be used either as a stand-alone application for running simulations, or as a library you call from your own code. It
provides a combination of extreme flexibility (through custom forces and integrators), openness, and high performance (especially on recent GPUs) that make it truly unique among simulation codes.

NEED HELP? Check out the discussion forums under Public Forums and the material from our workshops under Downloads.

GET STARTED QUICKLY: Tutorials and sample scripts to run OpenMM are available in the OpenMM Code Repository.

SOURCE CODE: The source code for OpenMM is available under Downloads and also from the Github Source Code Repository.

BENCHMARKS: A collection of benchmarks is available to show the performance of OpenMM simulating a variety of molecular systems.

CITING OPENMM: Any work that uses OpenMM should cite the papers listed on the Publications page.
