Initial tetrahedral mesh has 12,838 vertices, all on the boundary surface.

Triangular boundary surface mesh of the initial mesh.

There are 13,471 tetrahedral elements with minimum dihedral angle less than five degree.

After sink-insertion, 881 small slivers survived.

There are 12 slivers left after sliver-exudation.
Number of tetrahedra is decreased from 315,594 to 306,488.
Overall distribution of minimum dihedral angle is also improved.
