Salome Meshing .cgns export errors for SU2

Hello everybody,

I am trying to mesh a geometry to use in SU2 but even though I create group to have bondaries and export them in cgns format, SU2 doesn’t see them. I get this error every time : “The configuration file doesn’t have any definition for marker BAR_21-1100”

When I use this marker for a boundary condition I open the result in paraview and see there is only one boundary defined as BAR_21-1100 and nothing else.

How can I create boundaries in salome for SU2 to see them?
