WebHowever, the Berendsen thermostat can result in the flying ice cube effect, an artifact which can be eliminated by using the more rigorous … 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 …

WebAug 2, 2012 · converted to 1.19kCal/mole. My apologies. To determine whether it is because of 'flying ice cube effects', I am now using fix langevin+fix nph to replace fix npt. I tried NVE + Langevin (using a somewhat larger volume which was pre-equilibrated at NPT at a temperature of 310). This did not help.
WebMar 17, 2024 · The DoS plot illustrates the flying ice cube effect by showing a thermostat-dependent misproportion of high-frequency vibrational modes and low-frequency translations and rotations. The presence of metal surface modifies the water degrees of freedom and the entropy reflecting the mobility constraint due to the surface, and … 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 …

WebAbstract The flying ice cube effect is a molecular dynamics simulation artifact in which the use of velocity rescaling thermostats sometimes causes the violation of the equipartition theorem, affecting both structural and dynamic properties. The reason for this artifact and the conditions under which it occurs have not been fully understood. office furniture greenwood scWebWe show that the ‘local’ Langevin thermostat modifies the vibrational density of states of the polarisable solid, resulting in ITCs that depend very strongly on the damping constant of the thermostat. We report an increase of the ITC of up to 40% for short damping times. office furniture handicappedWebso-called flying ice cube. So this ensemble is very low efficient.
