Anisotropic tetrahedral meshing via bubble packing and advancing front

This paper presents a new computational method for anisotropic tetrahedral meshing. The method can control element anisotropy based on a speci ed 3×3 tensor eld de ned over a volumetric domain. Our method creates a tetrahedral mesh in two steps: (1) placing nodes at the centres of tightly packed ellipsoidal cells, called bubbles, in the domain, and (2) connecting the nodes by a modi ed advancing front followed by local transformation. The method creates a high-quality anisotropic mesh that conforms well to a speci ed tensor eld
