[Gmsh] Ask for help about triangle-tetrahedron mixed meshing

[Kingbo]

To whom it may concern,

Hello! I am a user of Gmsh and I've been using it for my research for a long time in the field of computational electromagnetics. Thank you for your contribution to this application!

Here I have two questions regarding Gmsh. First, I've already known that the 2D surface will be meshed into triangles and the 3D volume will be meshed into tetrahedrons in Gmsh. When a 3D volume is in touch with a 2D surface, they will share a certain face. Just on this interface, rather than the mesh shown in Fig.1, could you possibly make the triangles in the meshed tetrahedrons match up with those in the meshed surface like Fig.2 maybe through some appropriate settings? Second, how can I translate a closed surface (e.g. a spherical surface) into a volume (e.g. a solid sphere)?

This question is really important for my ongoing research. Could you please answer it when you're free? Thank you so much. Looking forward to your reply.
