[Gmsh] Erro: Could not recover boundary: error 3

[Hugo Fernando Maia Milan]

Hi,

I'm creating a mesh with 3 volumes. The first one is a small sphere. The second is a prolate spheroid which contains the sphere. The last one is a big sphere which contains the prolate spheroid.

I've achieve creating this mesh. However, I need the prolate spheroid with a lot of cylinders inside it. When I inserted the cylinders in the prolate spheroid and meshed in 3D I got the following:

Info    : Meshing 3D...
Info    : Delaunay Meshing 3 volumes with 1 connected components
Info    : Meshing volume 42754 (Delaunay)  This is the small sphere
Info    : Meshing volume 42755 (Delaunay)  This is the prolate spheroid with cylinders

Error   : Could not recover boundary: error 3
Error   : No tetrahedra in region 42754 0

I tried removing the small and big spheres but only when I removed the small and big spheres I could create the mesh with the prolate spheroid. Before this model, I was able to create a similar model, but with a square involving the prolate spheroid and without the small and the big spheres.

I'm running out of ideas. I looked for "Error   : Could not recover boundary: error 3" but I only found the source code. So, I don't know what kind of error is it. Does anyone have any idea?

Thank you,
Hugo
