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 … WebThe specific problems addressed in this work are velocity intialization techniques that are consistent with the CICMD equipartition priniciple, techniques for nulling momentum drift, …

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… WebMar 24, 2024 · We provide tantamount evidence that interfacial systems are susceptible to substantial flying ice cube effects and demonstrate that the traditional Nosé-Hoover … sono one speaker

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 14, 2016 · molecules to see the effect of different thermostats on COM momentum conservation, the flying ice cube effect, and a few other things (as inspired by what I … WebOne of the advantages of the MD simulation-based approach is that the temperature effect is naturally incorporated; we can map out the energy change in the free-energy landscape and thus obtain... small paint storage containers
