I successfully optimized my airfoil in adjoin solver, you can see the attached picture. However it is not possible to export the geometry in STL ( the button is shadow). I tried to export the mesh file-> write boundary mesh  to open it in spaceclaim. However spaceclaim will not open it. How can I get the optimalized airfoil shape ? I would be glad for spline, points, stl or simply anything I can work with. 

Thank you very much.
