Первая задача связана с обтеканием двумерным потоком идеальной жидкости цилиндрического тела, целью ее является расчет распределения скорости указанного потока. Результаты аналитического решения данной задачи сравниваются с результатами численного решения, полученного с использованием МКЭ. Показано, что результаты обоих решений хорошо согласуются между собой. Вторая задача - расчет профиля температуры в двумерном теле с заданными граничными условиями. Для решения этой задачи использовано двумерное уравнение Лапласа и метод разделения переменных. Полученное аналитическое решение также сравнивается с численным решением, найденным посредством МКЭ. Как и в предыдущем случае, отмечено хорошее согласование полученных результатов. Наконец, третьей задачей является описание распределения температуры в двумерном теле с внутренней теплоотдачей. Для моделирования применено двумерное уравнение Пуассона. Однако задача в данном случае не имеет аналитического решения. Анализ численного решения на основе МКЭ указывает на его корректность.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аналитическое решение</kwd><kwd>численное решение</kwd><kwd>уравнение Лапласа</kwd><kwd>уравнение Пуассона</kwd><kwd>метод потенциалов в теории теплопередачи и механике сплошной среды</kwd><kwd>метод конечных элементов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>analytical solution</kwd><kwd>approximate solution</kwd><kwd>Laplace equation</kwd><kwd>Poisson equation</kwd><kwd>potential formulation</kwd><kwd>the finite element method</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hughes T.J.R.
