Parallel computing in modeling solution process in micro level
The article was published in issue no. № 3, 2013 [ pp. 256-260 ]Abstract:The article describes software for modeling the processes ofdissolution and water absorption at the micro level using high-performance computing. A simulation model of water absorption and dissolution of solids based on probabilistic cellular automata was proposed, software implementation of the calculation algorithm using parallel computing was dis-cussed. The model is based on the probabilistic cellular automata. This paper describes the operating principle of cellular au-tomata, the possible states of the cells and rules of transitions from one state to another, the assumptions of the model. The model allows carrying out numerical experiments for the bodies with multi-component composition and complex geometry (solids, coated or irregular body shape). The mathematical model can be used for pre-generated structures and also generate a structure of solids immediately prior to settlement. After numerical experiments the dissolution process of solid polymer nanocomposite was modeled in one week interval. The simulation results were compared with the experimental data on the example of water absorption and dissolution of polymer nanocomposites, containing "soft" and "hard" inclusions. The ade-quacy of developed model for dissolution and water absorption was proved.
Аннотация:Описан программный комплекс для моделирования процессов растворения и водопоглощения на микроуровне с использованием высокопроизводительных вычислений. Предложена имитационная модель растворения и водопоглощения твердых тел и рассмотрена программная реализация расчетного алгоритма с применением параллельных вычислений. Имитационная модель построена на основе вероятностных клеточных автоматов. В статье описан принцип работы клеточного автомата, приведены возможные состояния клеток и правила пере-хода из одного состояния в другое, описаны допущения модели. Модель дает возможность проводить численные эксперименты для тел с многокомпонентным составом и сложной геометрией (твердые тела, покрытые оболочкой, или тела нестандартной формы). Математическая модельпозволяет использовать заранее сгенерированные структу-ры, а также генерировать структуры твердых тел непосредственно перед расчетом. В ходе численных экспериментов было смоделировано растворение твердого тела полимерного нанокомпозита в промежуток времени, составляющий одну неделю. Результаты моделирования сравниваются с экспериментальными данными на примере растворения и водопоглощения полимерных нанокомпозитов, содержащих мягкие и жесткие включения. Доказана адекватность разработанной модели растворения и водопоглощения. Описаны планы развития программного комплекса и математической модели.

using high-performance computing. A simulation model of water absorption and dissolution of solids based on probabilistic
cellular automata was proposed, software implementation of the calculation algorithm using parallel computing was dis-cussed. The model is based on the probabilistic cellular automata. This paper describes the operating principle of cellular au-tomata, the possible states of the cells and rules of transitions from one state to another, the assumptions of the model. The
model allows carrying out numerical experiments for the bodies with multi-component composition and complex geometry

The simulation results were compared with the experimental data on the example of water absorption and dissolution of polymer nanocomposites, containing "soft" and "hard" inclusions. The ade-quacy of developed model for dissolution and water absorption was proved.
