В основе подхода лежит интегральная форма закона Фарадея, применяемая к граням контрольных объемов. Дискретизация выполнена методом контрольного объема с использованием полностью неявной схемы и алгоритма переноса ограничения (CTA). В статье приводится вычисление метрических параметров расчетной сетки и коэффициентов дискретного аналога уравнения магнитной индукции в сферических координатах. Разобран специальный случай аппроксимации радиальной составляющей напряженности электрического поля на ребрах контрольного объема, лежащих на полярной оси (θ = 0,π). Разработанная численная схема реализована в авторском программном комплексе CVMHD для моделирования магнитогидродинамических течений и гидромагнитного динамо в сферических слоях.</p></abstract><abstract xml:lang="en" abstract-type="summary"><p>this paper presents a conservative finite-difference scheme for the magnetic induction equation in spherical coordinates. We based the approach on the integral form of Faraday’s law of induction applied to the faces of control volumes. We performed the discretization with the finite volume method using a fully implicit scheme and constrained transport (CT). We derived the grid metric terms and the coefficients of the discrete form of the magnetic induction equation in spherical coordinates. We analyzed a special case of approximating the radial component of the electric field at control-volume edges located on the polar axis (θ = 0,π). We implemented the resulting numerical scheme in the CVMHD code developed by the authors for simulations of magnetohydrodynamic flows and hydromagnetic dynamo in spherical shells.</p></abstract><kwd-group xml:lang="ru"><kwd>уравнение магнитной индукции</kwd><kwd>дискретизация</kwd><kwd>сферический слой</kwd><kwd>геодинамо</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magnetic induction equation</kwd><kwd>discretization</kwd><kwd>spherical shell</kwd><kwd>geodynamo</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках государственного задания НИЦ «Курчатовский институт» — НИИСИ по теме № FNEF-2024-0001 «Создание и реализация доверенных систем искусственного интеллекта, основанных на новых математических и алгоритмических методах, моделях быстрых вычислений, реализуемых на отечественных вычислительных системах» (1023032100070-3-1.2.1).</funding-statement><funding-statement xml:lang="en">this study is a part of the government contract No. FNEF-2024-0001 Development and Implementation of Trusted AI Systems Using New Mathematical and Algorithmic Methods; Fast Computing Models on Domestic Hardware with the Kurchatov Institute (1023032100070-3-1.2.1).</funding-statement></funding-group></article-meta></front><back><ref-list><ref id="ref1"><mixed-citation publication-type="other" xml:lang="ru">Zhang W., Jardin S., Ma Z., Kleiner A., Zhang H.
