Hi Fabien,

as you can see smesh is a 3rd party library taken from the Salome 
project. When checking the original sources on the Salome project side 
you will find the exact same code. Here is a link to their git repository:
https://git.salome-platform.org/gitweb/?p=modules/smesh.git;a=blob;f=src/DriverUNV/DriverUNV_R_SMDS_Mesh.cxx;h=95d6a2ff1cb4d6bd6c7e05bedb8e6682c5d167fe;hb=dcdb487253c9d718519f8fcafd1816686d10b375#l275

When looking further down the code you will see that for any other 
volume type it heavily changes the order of the nodes.

So, it's probably best to contact the Salome devs.

Regards,
Werner
