Hi again!

Now that I have my mesh connectivity output, I tried to mesh a CT voxelized
image of a sandstone porous sample. It has only one subdomain - the pores.
So, theoretically, I expect the resulting surface to be manifold and all
facets to have 3 neighbors. When I looked at the output, I saw that some
facets had more than 3 neighbors, and looking at the resulting mesh itself,
I saw that there are some regions where 4 facets meet at one edge. I wonder
whether there is any way to guarantee the manifoldness of the boundary
surface? Or should I then try to construct the surface mesh and feed it to
the 3d mesher afterward?
