Hi All,

I apologize in advance if I picked the wrong section of the forum.

Anyway I am Ansys newbie. I am struggling to import a txt data file into Design modeler.

I have created a NACA airfoil data file through AIRFOIL TOOL online, with a close trailing edge, of 100 points. I have transferred the data into Excel, splitting into the columns and created this format :

#Group #n.point #x #y #z
1 1 -1 0 0
1 2 0.999013 0.000119 0
1 3 0.996057 0.000476 0
1 4 0.991144 0.001067 0
1 5 0.984292 0.001883 0
1 6 0.975528 0.002918 0
1 7 0.964888 0.004158 0
1 8 0.952414 0.005591 0
( I have reported only the first 8 points)

In total have 5 columns.

I have saved the the file in txt format, as all the tutorials suggest.

Also I have had a training session few days ago and I m following the same procedure of the trainer, producing apparently the same txt file he produced but I am not able to create the geometry whilst if I import his file everything is of course fine.Looking at the two files they seem to me exactly the same, with the only difference due to different airfoils.

I do : Concept--> 3D curve-->coordinates file.

I keep getting this Error: Error Reading coordinates file.

Could anyone help me.

I would appreciate any help.

Thank you in advance for any reply.

Regards

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

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.

Hi Santuzza,

Try this :

• 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.

Let me know if you keep on facing the same problem because sometimes could depend on the cell formatting in Excel

Dear Antonio
I have the same problem, and did what you said, but again not solved. I attached the file.
