Initial tetrahedral mesh has 3,922 vertices, all on the boundary surface.

Triangular surface mesh of the initial mesh.

There are 4,532 tetrahedral elements with minimum dihedral angle less than five degree.

After sink-insertion, 173 small slivers survived.

Sliver-exudation eliminates all but one sliver.
Number of tetrahedra is decreased from 74,707 to 72,640.
Overall distribution of minimum dihedral angle is also improved.
