The surface mesh is broken on 3D mesh adaptation
 

Dear developers,

I have run the inviscid ONERA M6 Wing case with mesh adaptation, but some error messages appear:

-----------------------------------
Number of elements to adapt: 262241
Homothetic grid adaptation
Preprocessing for doing the implicit smoothing
The surface element (0, 5051) doesn't have an associated volume element.
-----------------------------------

Then I set SMOOTH_GEOMETRY = NO and the mesh adaptation can run successfully, but I find the some surface elements are not correct. The picture of the surface adapted is attached.

thanks,

Ervas

Could you please try with

% Before each computation, implicitly smooth the nodal coordinates (NO, YES)
SMOOTH_GEOMETRY= NO
%
% Adapt the boundary elements (NO, YES)
ADAPT_BOUNDARY= NO

Best Regards,
Francisco
