The input model was originally from Jonathan Dantzig.

Initial tetrahedral mesh has 11,525 vertices, all on the boundary surface.

Triangular surface mesh of the initial mesh.

There are 846 tetrahedral elements with minimum dihedral angle less than five degree.

After sink-insertion, 253 small slivers survived.

Sliver-exudation eliminates all but three slivers.
Number of tetrahedra is decreased from 93,186 to 90,969.
Overall distribution of minimum dihedral angle is also improved.
