PLUMED is an open source library for free energy calculations in molecular systems which works together with some of the most 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.
In May 2014 the second PLUMED tutorial and user meeting was held in Belfast, sponsored by CECAM. The material of the tutorial is included in PLUMED2 v.2.1!
In October 2013 we have released a completely redesigned version of the code: PLUMED2!
