WebApr 30, 2013 · Internal coordinate molecular dynamics (ICMD) methods provide a more natural description of a protein by using bond, angle, and torsional coordinates instead of a Cartesian coordinate representation. Freezing high‐frequency bonds and angles in the ICMD model gives rise to constrained ICMD (CICMD) models. There are several theoretical … WebJul 25, 2024 · The flying ice cube effect is when the kinetic energy leaks into the translations and rotations. In a constant energy simulation (NVE) this must come at …

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 WebSep 26, 2003 · The Hamiltonian formulation of the Gaussian isokinetic (GIK) thermostat [C. P. Dettmann and G. P. Morriss, Phys. Rev. E 54, 2495 (1996)] is extended to generalize the coupling of a physical system to a heat bath in molecular dynamics (MD) simulations. This extension gives a theoretical basis for the statistical ensemble recently proposed to … WebMay 12, 2024 · $\begingroup$ @curio you can add a link to the answer by Hess as an answer to this question, after clicking the "community wiki" box, to indicate that this is a link to an answer by the community rather than by yourself.
