Sub-mesh is a mesh on a geometrical sub-object created with algorithms

If a geometrical sub-object belongs to several geometrical objects
having different meshes or sub-meshes, it will be meshed with the

its own different sub-mesh, will be meshed using algorithms and
hypotheses of any of the two, chosen randomly. This indeterminacy can
