摘要: Abstract We propose an anisotropic refinement strategy which is specially designed for the efficient numerical resolution of internal and boundary layers. This based on directed pairs triangles together with adaptive multilevel grid orientation. Compared to usual methods, new ends up in more stable accurate solutions at much less computational cost. demonstrated by several examples.
