What do you mean by missing parts please ?

Yes it is a domain with sharp edges if you want the have the edges in 
the mesh. The actual implementation is designed for smooth surfaces only.

If you try to mesh a cube, you will only have an approximation of the 
edges (the element size near the edges depends of the surface 
approximation error criterion).
