It is also sometimes called constant temperature molecular dynamics (CTMD). In NVT, the energy of endothermic and exothermic processes is exchanged with a thermostat. A variety of thermostat algorithms are available to add and remove energy from the boundaries of an MD simulation in a more or less realistic way, approximating the canonical ...
Popular techniques to control temperature include velocity rescaling, the Andersen thermostat, the Nosé–Hoover thermostat, Nosé–Hoover chains, the Berendsen thermostat and Langevin dynamics. The central idea is to simulate in such a way that we obtain a canonical ensemble, where we fix the particle number N {\displaystyle N} , the volume ...
The Berendsen thermostat [1] is an algorithm to re-scale the velocities of particles in molecular dynamics simulations to control the simulation temperature.
Constant-pressure simulations are useful for determining the equation of state of a pure system. Monte Carlo simulations using the -ensemble are particularly useful for determining the equation of state of fluids at pressures of around 1 atm, where they can achieve accurate results with much less computational time than other ensembles.
Langevin dynamics attempts to extend molecular dynamics to allow for these effects. Also, Langevin dynamics allows temperature to be controlled as with a thermostat, thus approximating the canonical ensemble. Langevin dynamics mimics the viscous aspect of a solvent.

ms2 contains two molecular simulation techniques: molecular dynamics (MD) and Monte-Carlo. ms2 supports the calculation of vapor-liquid equilibria of pure components as well as multi-component mixtures. Different Phase equilibrium calculation methods are implemented in ms2.
Pretty good version given Darnold’s youth and how the supply-side dynamics of the league’s quarterback market decidedly seem to be working to his advantage. Maybe he cost himself a long-term ...
