The input model was originally from Timothy J. Baker.

Initial tetrahedral mesh has 13,474 vertices, all on the boundary surface.

Triangular boundary surface mesh of the initial mesh.

There are 10,076 tetrahedral elements with minimum dihedral angle less than five degree.

After sink-insertion, 733 small slivers survived.

There are 6 slivers left after sliver-exudation.
Number of tetrahedra is decreased from 317,565 to 308,801.
Overall distribution of minimum dihedral angle is also improved.
