Triangular Mesh Generation over Arbitrary Two-dimensional Domain
Xiong Yue · Journal of National University of Defense Technology · 2008
A refinement-based triangular meshing algorithm is proposed to generate finite element meshes of arbitrary two-dimensional domains.The boundary is triangulated by the ear-removal method,constructing an initial mesh with coarse elements.To meet the pre-specified sizing requirement by refining the initial mesh,a novel mesh refinement method,Delaunay-optimized bisection,is presented.By combining global-longest-edge bisection with Delaunay edge swapping,well-shaped triangular elements are constructed.Meshing examples are presented along with mesh statistics,showing that the presented algorithm is capable of generating quality finite element meshes for arbitrary 2D domains.
