Dear all,
I hope you are all okay.
I am dealing with the problem in which I need to export a mesh from fluent for the su2 solution.

Actually, I am able to export cgns file from fluent and this mesh seems to be readable for SU2.
Indeed SU2 can read this mesh and create FFD box without an issue.

However, "interior-default" is left as a naming for the FACES of the interior tetrahedrons.
When I label "interior-default" as MARKER_INTERNAL solution starts but diverges.

When similar mesh is exported directly from ANSYS mesher as cgns, there is no (recognized) FACES of the interior tetrahedrons in the solution domain and SU2 is converge with no issues.

Any help will be appreciated!
Thanks
