摘要

在这项工作中,我们针对密度随温度变化的高度非线性流动温度模型,开发了采用目标导向误差控制的自适应方案。采用双加权残差法计算误差指标,以引导网格细化和求解器控制。误差指标用于采用自适应算法,并通过若干数值测试加以证实。在此过程中,误差减小和效果指数可用于确定我们框架的稳健性和效率。

Mathematical modeling and numerical multigoal-oriented a posteriori error control and adaptivity for a stationary, nonlinear, coupled flow temperature model with temperature dependent density
In this work, we develop adaptive schemes using goal-oriented error control for a highly nonlinear flow temperature model with temperature dependent density. The dual-weighted residual method for computing error indicators to steer mesh refinement and solver control is employed. The error indicators are used to employ adaptive algorithms, which are substantiated with several numerical tests. Therein, error reductions and effectivity indices are consulted to establish the robustness and efficiency of our framework.
