PLUMED is an open source library for free energy calculations in molecular systems which works together with many popular molecular dynamics engines. Free energy calculations can be performed as a function of many order parameters with a particular focus on biological problems, using state of the art methods such as metadynamics, umbrella sampling and Jarzynski-equation based steered MD. The software, written in C++, can be easily interfaced with both Fortran and C/C++ codes.
