1. Introduction

OpenMM consists of two parts:

  1. A set of libraries that lets programmers easily add molecular simulation features to their programs
  2. An “application layer” that exposes those features to end users who just want to run simulations

This guide is divided into three sections:

  • Part I (Chapters 2-6) describes the application layer. It is relevant to all users, but especially relevant to people who want to use OpenMM as a stand-alone application for running simulations.
  • Part II (Chapters 7-16) describes how to use the OpenMM libraries within your own applications. It is primarily relevant to programmers who want to write simulation applications.
  • Part III (Chapters 17-21) describes the mathematical theory behind the features found in OpenMM. It is relevant to all users.

1.1. Online Resources

You can find more documentation and other material at our website http://openmm.org. Among other things there is a discussion forum, a wiki, and videos of lectures on using OpenMM.

1.2. Referencing OpenMM

Any work that uses OpenMM should cite the following publication:

P. Eastman, J. Swails, J. D. Chodera, R. T. McGibbon, Y. Zhao, K. A. Beauchamp, L.-P. Wang, A. C. Simmonett, M. P. Harrigan, C. D. Stern, R. P. Wiewiora, B. R. Brooks, and V. S. Pande. “OpenMM 7: Rapid development of high performance algorithms for molecular dynamics.” PLOS Comp. Biol. 13(7): e1005659. (2017)

We depend on academic research grants to fund the OpenMM development efforts; citations of our publication will help demonstrate the value of OpenMM.
