Hi,

I have posted about my problem already here 
http://cgal-discuss.949826.n4.nabble.com/3D-volume-mesher-ignoring-small-subdomains-td4655756.html 
but thought I reformulate it:

I have a labeled image as input to make_mesh_3 which contains a small 
sub-domain (label 2) inside a larger domain (label 1). Small meaning the 
its characteristic size is about two orders of magnitude smaller then 
the embedding domain.

So my question is, what are the criteria for refining cells in the large 
domain to ensure that they do not "shadow" a complete small sub-domain? 
I would like to be able to set a large maximum cell size for the large 
domain and a suitable cell size for small sub-domain. When setting the 
cell and facet criteria in such a way, my small sub-domain is ignored 
however.

Any tips would be highly appreciated.

Thanks,

Sascha
