Используется метод молекулярной динамики, метод Бокса-Мюллера для генерации случайных величин из нормального распределения, метод погруженного атома, метод сопряжённых градиентов Флетчера-Ривса, метод аппроксимации параболой и метод золотого сечения для поиска минимума функции, метод Верле для скоростей.Результаты. Создана программа для молекулярно-динамического моделирования с предварительной релаксацией атомного блока. Для блоков разных размеров рассчитаны постоянная решётки и поверхностная энергия связи. Показана корректность модели.Теоретическая и практическая значимость. Результаты могут быть использованы другими исследователями при разработке похожих моделей. Кроме того, созданная в работе модель будет нами использоваться на практике в будущих работах для исследования эмиссии атомов при распылении с грани (001) Ni.</p></abstract><trans-abstract xml:lang="en"><p>Aim is to create a molecular dynamics model of the (001) Ni atomic block that can be used to study sputtering.Methodology. The molecular dynamics method, the Box-Muller method to generate random numbers from normal distribution, the embedded atom method, the Fletcher-Reeves conjugate gradient method, the parabola approximation and the golden section methods to find the minimum of a function, and the Velocity Verlet method are used.Results. A program for molecular dynamics modeling with preliminary relaxation of the atomic block has been created. The lattice constant and surface binding energy were calculated for blocks of different sizes. The correctness of the model has been shown.Research implications. The results can be used by other researchers in developing similar models. In addition, the model created in the work will be used in practice in our future works to study the ejection of atoms during sputtering from the (001) Ni face.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молекулярная динамика</kwd><kwd>релаксация системы</kwd><kwd>метод сопряжённых градиентов</kwd><kwd>многочастичный потенциал</kwd><kwd>постоянная решётки</kwd><kwd>поверхностная энергия связи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molecular dynamics</kwd><kwd>system relaxation</kwd><kwd>conjugate gradient method</kwd><kwd>many-body potential</kwd><kwd>lattice constant</kwd><kwd>surface binding energy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена с использованием оборудования Центра коллективного пользования сверхвысокопроизводительными вычислительными ресурсами МГУ имени М.
