<p style="margin-bottom: 0in;">Thanks.</p>
<p style="margin-bottom: 0in;">My doubt has been clarified. I though
that only the surfaces included in the surface loop were considered
by the algorithm. I could not understand why the second volume was
modifying the mesh of the first volume.</p>
<p style="margin-bottom: 0in;">I also had a similar problem with
single volumes that are thin (like layers or shells not modelled
using surface meshes) but I assumed that it was a normal error and I
should use another meshing algorithm like an extrusion. I guess that
it can also be related with the small distance between surfaces.</p>
