Abstract

Многомасштабный способ конечных объемов предложен для эффективного решения больших неоднородных задач; его обычно используют для уравнений давления и представлений полей консервативных потоков, используемых в задачах переноса. Он основан на гипотезе, заключающейся в том, что мелкомасштабная задача может быть описана множеством локальных решений, связанных консервативной многомасштабной задачей. В численно сложных случаях более точное приближение о локализации используют для получения хорошего приближения мелкомасштабного решения. В соответствии с осуществлением предложен способ для итерационного уточнения граничных условий локальных задач, являющийся чувствительным к структуре данных основополагающего многомасштабного способа конечных объемов, при этом используют способ проекции в подпространство Крылова для получения безусловно устойчивой схемы и ускоренного схождения. В одном осуществлении используют оператор многомасштабного способа конечных объемов. В качестве варианта оператор многомасштабного способа конечных объемов сочетают с оператором, получаемым из задачи, решаемой для построения поля консервативных потоков.
