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. http://www.cchem.berkeley.edu/molsim/personal_pages/berend/articles/2024/anomalous-effects-of-veloci.html

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… only tucumanWebAn Explanation of the Flying Ice Cube Effect: How Simple Velocity Rescaling and the Berendsen Thermostat Lead to the Violation of the Equipartition Theorem 6 Brown, Aidan Simon Fraser University Distributing dissipation to maximize steady-state flux 7 Dasbiswas, Kinjal University of Chicago Topological boundary modes in soft active matter only t soundbox
