Would you be interested in contributing it to the code gallery?
I'd love to contribute after I work it out!
Jie,
that would be fantastic -- please do let us know
Hi Martin and Wolfgang
Thank you very much for the helpful comments and references. I'll start
to read the works you mentioned.

Hi Jie,
One needs to move some of the vertices around. I have some code that
does generate this geometry in one of my projects:

(check the create_triangulation function)
The mesh that comes out from this code is

So you are running into the error with only one MPI process as well?
Then, you should be able to omit
