Webso-called flying ice cube. So this ensemble is very low efficient. Actually this thermostat do not generate any ensembles, neither microcanonical nor canonical ensembles. ... – Berendsen: flying ice cube effect (energy pumped into low-frequency modes) – Nos´e-Hoover: potential non-ergodicity, inaccurate integration of heat bath In molecular dynamics (MD) simulations, the flying ice cube effect is an artifact in which the energy of high-frequency fundamental modes is drained into low-frequency modes, particularly into zero-frequency motions such as overall translation and rotation of the system. The artifact derives its name from a particularly noticeable manifestation that arises in simulations of particles in vacuum, where the system being simulated acquires high linear momentum and experiences extremely d… charter corporate office charlotte nc https://ajrnapp.com
