Dear colleages

I am trying to build the mesh for a slice with a pentagonal hole.
GMSH runs properly with good quality tets but when trying to read it from
freefem++ the error is:

" Bad orientation: The adj border element  defined by [  16 246 ]  is
oriented in the same direction in element 3922 and in the element 446
****** bug in mesh construction? orientation parameter?
  current line = 12 mpirank 1 / 2
Can you give any advice on this?

Thanks in advance
