    Molecular dynamics of potential models with polarizability: comparison of methods

  • Original language description

    Three methods for molecular dynamics of models with induced dipoles are optimized for accuracy and performance and compared: the predicted iteration method, the always stable predictor-corrector method, and the extended Lagrangian method (Car-Parrinelloapproach). The comparison criteria include thermodynamic quantities (energy, pressure, averaged induced dipoles), control quantities (total energy conservation, energy equipartition, errors in induced dipoles), and computer time. We recommend the alwaysstable predictor-corrector method as a compromise between accuracy, speed, and simulation consistency.

    Molekulova dynamika potencialovych modelu s polarizovatelnosti: srovnani metod

  • Czech description

    Optimalizovali a porovnali jsme tři metody pro molekulovou dynamiku modelů s indukovanými dipóly: metodu predikovaných iterací, vždy stabilní metodu prediktor-korektor a metodu rozšířeného Lagrangiánu (přístup Cara-Parinella). Kritéria srovnání zahrnujítermodynamické veličiny (energii, tlak, střední indukovaný dipól), kontrolní veličiny (zachování celkové energie, ekvipartiční teorém, chyby indukovaných dipólů) a počítačový čas. Doporučujeme vždy stabilní metodu prediktor-korektor jako kompromis mezi přesností, rychlostí a konzistencí simulace.
