Hi Tang! If parts of your subdomains are missing from the final mesh, you should check the following hints:
* specified bounding sphere/box must be slightly larger than all input.
* initial points must sample all surfaces with several points each.
You could detect sharp features in your input meshes by checking angles at every edge. Insert the sharp edges as initial points and edges. You should use the _with_features classes for this. The existing polyhedral domain with features already has a method for detecting sharp features.
Best regards.

Dear Prof. Göran Wallgren,
Thank you very much for your kindly reply. I have tested the example "mesh_implicit_domains.cpp" but found it can't generate multiple domains meshes with the given feature:
http://cgal-discuss.949826.n4.nabble.com/Question-about-CGAL-example-mesh-implicit-domains-td4659082.html
Could you please help me to take a look at it?
On the other hand, I read the post you put here and he said that he will keep all edges in the input polyhedra in final meshes. Is it possible to just keep the boundary features but still refine the surface facets according to the mesh size and mesh quality specified?
Thanks,
Tang Laoya
