Abstract
A strategy is presented to define background meshes based on crystal lattices. Crystal-based background meshes have much better initial distribution of minimum dihedral angles than regular background meshes, facilitating the optimization procedures that rely on previously defined tetrahedral meshes. In addition, these background meshes can reduce significantly, or even eliminate, the number of slivers generated during a Delaunay triangulation
