Показано, что моделирование с помощью МГЭ может быть более эффективным по сравнению с традиционно используемым моделированием с помощью метода конечных элементов (МКЭ). Рассмотрена тестовая задача расчета акустического поля, создаваемого ультразвуковым волноводом в полубесконечной жидкой среде. Задача решена с помощью МГЭ и МКЭ. Проведен сравнительный анализ результатов. При моделировании с помощью МГЭ дополнительно использован метод зеркального источника, позволяющий избежать рассмотрения бесконечной границы жидкости.</p></abstract><trans-abstract xml:lang="en"><p>The article studies possibility of application of boundary element method (BEM) to modelling of acoustic fields generated during ultrasonic angioplasty. It is shown that modelling by means of BEM can be more efficient that traditionally used modelling by means of finite element method (FEM). Test problem of calculation of acoustic field created by ultrasonic waveguide in semi-infinite fluid medium is considered. The problem is solved by means of BEM and FEM and comparative analysis of results is provided. Modelling by means of BEM additionally involves application of mirror source method for avoidance of treatment of infinite fluid boundary.</p><p> </p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wylie, M.
