Для решения задачи на мелкой сетке (эталонное решение) используется смешанный метод конечных элементов (Mixed FEM), где аппроксимация скорости реализована с помощью элементов Равиарта — Томаса наименьшего порядка и кусочно постоянных базисных функций для давления. Решение на грубой сетке выполнено с использованием смешанного обобщенного многомасштабного метода конечных элементов (Mixed GMsFEM). Поскольку перфорации оказывают огромное влияние на процессы в среде, то возникает необходимость вычисления дополнительного базиса, учитывающего влияние перфораций на решение задачи. Приводятся результаты численного эксперимента в двумерной области, подтверждающие работоспособность предложенного многомасштабного метода. </p></abstract><trans-abstract xml:lang="en"><p>We consider the solution of an elliptic equation in mixed formulation in a perforated medium with inhomogeneous Dirichlet boundary conditions at the perforation boundary. To solve the problem on a fine grid (reference solution), the mixed finite element method (Mixed FEM) is used, where the approximation of speed is implemented using Raviart–Thomas elements of the smallest order and piecewise constant basis functions for pressure. The solution on a coarse grid was obtained with the use of the mixed generalized multiscale finite element method (Mixed GMsFEM). Since the perforations have a great influence on the processes in the medium, it is necessary to calculate an additional basis, taking into account the effect of perforations on the solution. The article presents the results of a numerical experiment in a two-dimensional domain which confirm the efficiency of the proposed multiscale method. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>смешанный обобщенный многомасштабный метод конечных элементов</kwd><kwd>смешанный метод конечных элементов</kwd><kwd>эллиптическое уравнение</kwd><kwd>дополнительная многомасштабная базисная функция</kwd><kwd>перфорированная область</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mixed generalized multiscale finite element method</kwd><kwd>mixed finite element method</kwd><kwd>elliptic equation</kwd><kwd>additional multiscale basis function</kwd><kwd>perforated region</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет гранта РНФ 17–71–2005 (постановка задачи и теоретическая часть) и мега-гранта Правительства РФ № 14.Y26.31.0013 (численный алгоритм).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Le Bris L., Legoll F., Lozinski A.
