<span lang="EN-US" style="font-family:"Times New Roman","serif";color:black">Here I have two questions regarding Gmsh.
<b>First,</b> 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? <b>Second,</b> how can I translate a closed surface (e.g. a spherical surface)
into a volume (e.g. a solid sphere)?</span><span style="color:black"><o:p></o:p></span></p>
