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
