我们提出了一种各向异性加密策略，该策略是专门为内部层和边界层的有效数值分辨率而设计的。该策略基于对单个三角形的定向精化和自适应多级网格定位。与通常的方法相比，新的各向异性加密以更少的计算代价得到了更稳定和更精确的解。几个数值算例说明了这一点。
We propose an anisotropic refinement strategy which is specially designed for the efficient numerical resolution of internal and boundary layers. This strategy is based on the directed refinement of single triangles together with adaptive multilevel grid orientation. Compared to usual methods, the new anisotropic refinement ends up in more stable and more accurate solutions at much less computational cost. This is demonstrated by several numerical examples.
