Hi
I have similar problem with my CFD 3d curve, however I'm using the S814 Airfoil, and I keep getting the same error: "Error reading coordinates file"

my cordinate file and a image is capturd in ansys is attached, I'm not quite sure what is wrong with my airfoil coordinates as it does not create 3D curve.

Appreciate all the helps in advance.

guys, i am a very new user, when i try to import coordinate file from txt, it says i have "error reading coordinates file". i dont know where is the fault...im using airfoil data for SD7062. Please help me anyone as soon as possible. i ll be very grateful.

Delete the last point (last line with point # 61), it is duplicated. Only left 60 points.

it totally worked but the the airfoil is not joined fully, like at the trailing edge, bottom surface it is not connected to the tip ...

You can split your airfoil in two lines (upper and lower). You text file looks like:

#Group Point X_Cord Y-cord Z-cord
1 1 0.00000 0.00000 0
.
.
.
1 31 1.00000 0.00000 0
#Group Point X_Cord Y-cord Z-cord
2 1 0.00000 0.00000 0
.
.
.
2 31 1.00000 0.00000 0

but wouldnt it change the airfoil's shape ? cause the shape of the airfoil is like the one in the attachment...so i dont really know if at the leading edge exactly at the origin. sorry that im asking too many questions..

[Hybrid]

it will not change the shape at all.. You have to take the coordinates of the upper surface and lower surfaces separately, starting from 0.0 until 1.0.

If you feel any difficulty in this method, you can manually join the airfoil lower point with the trailing edge by using my previous advice.

Thank u so much Ali...if it wasnt for ur help, i wouldnt be graduating...
Im so grateful to have found this forum...Thank you so muchh...

Hello to all of you.
I need some help. When i go to make a 3D Curve at Ansys he send me a message
{ Error Coordinating Files}
Below the file with the coordinates.

NACA 0012 WITH ANGLE OF ATTACK.txt

Thanks a lot guys!

Thanks a lot guys!

Just put an # on the first line (header)

[F1 Master]

It doesn't work.... put the # at the beginning but again shows me this message...

Hey everyone im trying to import my NACA4402 coordinate to ansys fluent it didn't accept it and it shows error message like duplicate line 191.....
Please Help me to solve the errror ...

I am learning Ansys.
I can't convert the txt file to a 3D curve !
I tried replacing the dots with commas.
It shows "error reading co ordinates file" !
I am using workbench 16.
The file is attached. Plz help.

Hello everybody,

i am a new user to Ansys Workbench 18.2. And i am also a new user to this great CFD Forum which i found. This is my first post in this forum, so I'd like to apologize for any inconvenience. Please just correct me :-). I am from Germany but i use the english language in Ansys.
I have to create a NACA2412 profil with the DesignModeler in Ansys.
When i select Create -> Point -> Coordinate File and Coordinate Unit: Meter i get the follow warning:
"Warning: One or more points exceed modeler's size box
Context: Point Feature Point1"
But if i select Millimeter as Coordinates Unit i don't get this warning. This is the first thing what seems strange to me.
When i want to create a 3D Curve and select the Coordinates Files i get the Error: Error reading Coordinates File. Here, it doesn't matter if i chose meter or milimeter. I get the error with both settings.
In the appendix you can find the txt file of the point-coordinates an a screenshot of the Points created in Ansys.
Sorry but my english isn't that perfect. I am very grateful for any help.

Kind regards
Daniel
