​Dear Guilllaume,

Attached the .msh file which CreateTopology do not work on it. Currently I
am working with a windows 7 machine. It would be really nice if you will do
some experiments with it.

And I will try the other options which you mentioned. Once I find a way to
solve my problem, I will inform you.

best,
Siming
