Hi

when i am importing a coordinate file using 3D curve option a window is popping out saying that error reading coordinate file.
Can u plzz give a solution for this problem.
I had attached the file also

What code is this for?

[pradeepsama]

these are airfoil coordinates.
can anybody help plzz

[lcarasik]

You need to post more information such as what code you are using to get help. You haven't provide any information.

[pradeepsama]

i am opening the work bench and using modal analysis
and i am importing the coordinate file by first making proper arrangement of columns in ms excel and after importing the file when i am joining the points by "lines through point" option i am able to join some point after that i am getting an error called points are self intersecting.

[Kapi]

remove the last line of code and try once more, it mite solve

Hi all

I have the same error of this topic DS error reading coordinates file.

I dont understand the file NACA-4412 is works fine to import but my other file is get this error.

I search in the CFD forum but nothing can solve my problem here some solution:

The txt file must be saved as ANSI not UNICODE(it saves like that by default)

• Put comment # at the beginning of each column( such as #x, #y etc)

• The last row must be 1 0 that means erase the column relative to x,y,z coordinates because they are the same of the first one( I am assuming that you have created an airfoil with closed trailing edge)
• Save the file as ANSI not unicode.

I dont know where my error in the file Clark Y.txt


I generate from the site aerofoil tools


my ansys version is 17.1, excel version 2013.


I salve the file in txt tab delimited and nothing works.


thanks

Hi Pradeep,

I had a similar error. The fix was to use same format of numbers as used in ansys; that is if a comma or dot is the correct input for decimal place.

That's the answer.

when u download coordinates from airfoil plotter
you will have repeated coordinates in the excel file , you just need to remove that one repeated co ordinate point , thats simple

Hey guys!
So im trying to upload this coordinate file in DM, but when I do I get the error that id is found in coordinates file. I have tried both commas and points but it didn't work. can anyone help me? I dont know how to add the file so ill do it like this:

Thanks a lot Torchbearer! Saved my day

[SSG_NJ]

I tried every known solution on the internet, and exactly 0 of them worked.

How I fixed my issue, was:
1. Go to airfoiltools.com and get clark y coordinates
2. On the right hand side of the screen, click "Send to airfoil plotter"
3. On the next screen, choose "CSV file of coordinates"
4. Open the file, create a new z coordinate with 0s
5. Make sure all 3 coordinates have same number of significant digits
6. Convert file to tab delimited (.txt)
7. Open DesignModeler, change units to mm
8. Concept -> 3D curve-> Choose coordinates file.

DONE.

I was struggling with this for days!!! Hope this helps someone else.

hello i have same problem for MH-45

Hi there.
Perharps i’m joining the thread a little bit late, but could you explain me how did you make the NACA-4412 archive in more detail? I’ve been struggling with the 3d curve problem for weeks, and knowing how to make propper archives would be really helpful, for I need it for a research proyect.
Thanks!
