Helly everybody,

as a complete beginner do ANSYS (FLUENT) I try to follow a tutorial on an airfoil with ANSYS14.
To begin with the geometry of a NACA 7420 shall be imported as a 3D-curve from a .txt file (attached).
When I import this file I get a Reading Error and after generation the
"Error: Duplicate Coordinates found in Coordinates File
Context:Curve Feature Curve5
File:<path>
Line:61"

I cant see any duplicate coordinates which I figured to be coordinates of the same group and point number nor geometrically the same coordinates.
Line 61 is the line in wich the curve's coordinates are the origin.
If I change them slightly the Error still appears
If I delete them I then get the
"Error: Points in Coordinates File are outside valid range
Context: Geometry Engine, while generating Feature Curve5"

Since I could not find the definition of the "valid range" neither in the ANSYS help nor in other threads or by experimenting I hope for your help.

(If I missed to explain relevant aspects of the problem please ask for more information)

Thank you for thinking about it
