WebThis command creates an OpenMM System object from the information stored in top. It contains multiple Force instances for the bonds, angles, periodic torsions, and nonbonded (electrostatic and van der Waals) interactions. It is in this function that we define the potential parameters we want to use. WebTwo Metadynamics examples are included in the Examples/User/Meta directory. In the first example, Metadynamics is used to sample the free energy surface of a two-dimensional particle undergoing Langevin dynamics. This example is found in the Single_Atom directory and uses LAMMPS. The files included are described below: smart gear wireless thermometer manual
