Probably failing CGNS export?
 
Hey guys,

I am currently meshing a ship with Hexpress and I'm experiencing some strange "holes" in the mesh, which create a wake and have an absolutely wrong air/fluid concentration.
In postprocessing with Paraview I see these holes at the edge of the Kelvin-angle refinement and I also tried reimporting the CGNS to Hexpress, in which I see boundaries of the domain at the exact same location as in Paraview (which disproves the theory of a display error in Paraview).
I am refining the free surface as well as the Kelvin-angle by an internal surface.

Iguess something in the CGNS-export went wrong and created these wrong cells.

Did someone experience a similar effect? What causes these strange defects?

Hexpress Version is 2.11-3
