Hi everyone,
I'm using CGAL's 3D mesh generation, now I'd like to do the following:
Suppose I have a 3D image, lets say it represents a sphere in a cube (the cube is represented by the rectangular nature of the image, of course). Now I know how to generate a mesh for the sphere. I also know how to generate a mesh filling the full cube with two regions/materials, let's say "sphere" and "water around sphere filling cube".
Now, I'd like to extend it a bit: Let's say, the top face of the cube is used to impose boundary conditions for a subsequent FEM simulation, and the bottom side is used to impose other boundary conditions. How can I designate the facets on top and bottom to the respective boundary type?
Furthermore, it could be that the sphere is not fully inside the cube and will also get some facets for boundary conditions. How could I do that?
I do not expect a full solution, rather some guidance at which parts of the meshing package I should have a look.
Best regards
Michael
