[Gmsh] No tetrahedra in region 10 problem

[Purbasha Garai]

Hello everybody,

I have a .geo file of a nerve (cylinder). While trying to get a 3D mesh in
gmsh, I am getting an error 'No tetrahedra in region 10' . I understand
that I have to add the surfaces to the end. But I am unsure how do I do the
same. I wrote .geo file to extract the information from .stl file (surface
mesh).

I am attaching the .geo file and .stl file for your review.

Your help and advise will be really appreciated.

Thank you so much


Regards
