Dear Vishal,

Hexahedra should work fine. It’s not immediately obvious what your issue is. Can you send me your session files so I can look into your issue?

FYI, we also have a new NekMesh mailing list which this thread might be appropriate for.

Cheers,

Subject: [Nektar-users] curved elements and BL splitting

Hi all,

This is regarding NekMesh utility. 

I would like to mesh a pipe which has coarse elements to begin with (inlet cross section shown in figure). In order to make the outer surface smooth I applied "spherigons" which worked fine (see attached). 

However, when I try to use "boundary layer splitting", NekMesh says:

No elements detected to split.

The element type on the outer surface are hexahedra. Is it the problem? 

Can anyone suggest a way out?

Cheers,

Vishal
