论文摘要
我们为近似值的外部正常通量提供了基于残差的A-tosterii误差估计,以{带有可变系数的扩散问题}。通过分析伴随问题的解决方案,我们表明批量中的误差指标可能被定义为更高的阶段,而距离接近边界的误差指标可能会导致更多的经济网格。该理论用一些数值示例进行了说明。
We derive a residual based a-posteriori error estimate for the outer normal flux of approximations to {the diffusion problem with variable coefficient}. By analyzing the solution of the adjoint problem, we show that error indicators in the bulk may be defined to be of higher order than those close to the boundary, which lead to more economic meshes. The theory is illustrated with some numerical examples.
