A Simple Anisotropic Mesh-Refinement Strategy for Triangular Elements in 2D
Figure 4
Local subdivision of triangular elements with given edges to refine. 1, 2, or 3 edges can be marked for subdivision (indicated with circles, or ). In the case that two edges are marked for refinement the sub-triangulation depends on which of the two edges has the highest error indicator (marked with filled circle, ).
