I downloaded airfoil files having .dat extension from
http://m-selig.ae.illinois.edu/ads/c..._database.html
....when i try to import it to ICEM 14 it shows nothing......
I also tried by removing name at top of dat file..but nothing happen...
not even it shows error.....(This is when u understand importance of error !!!)
Guide me.....I have searched a lot....

[kell$]

One way I found is.....just copy all co-ordinates to excel file and create 3rd column of 0 co-ordinates...then saving it in .txt......Done now i can see points..
But I hope that someone have better solution than this...because it is very tedious task when you have too many airfoils...

As kell$ said, you should add a third column which contain the third coordinate, in this case the z axis.
you can add a fixed value which will be the position of the airfoil on the z axis.

Another thing to do is to add extra line at the beginning of the text file which contain the coordinate of the airfoil that define number of points and how many curves you want to creat.
for example if you have an airfoil which contain 100 points, and you want to creat the airfoil from single curve , the first line will contail this ( 100 1 ) that mean you have 100 points and you want ICEM to make one curve from them.

On the otherhand if you want 2 curves you will do like this ( 50 2 )which mean you want the airfoil to consists from 2 curves upper and lower each have 50 points.

Hay all,

I have nothing when I read the attached coordinate of RAE2822 (when I set 3D on workbench geometry property), but I got error message when I set 2D on workbench geometry property.

Anyone could help me, many thanks

Hi Prasetyo,

I have just realize you have posted another similar post to "[ICEM] Importing Points for Airfoils" in this thread.

As I can see on your .txt file, you are using the same data structure that you used for ICEM CFD. Ansys workbench (Design Modeler or Meshing) uses a different data layout.

Have a look at these threads:

Importing Points in Design Modeler

How to insert points to DesignModeler of Ansys?

Hope this helps you

Many thanks for your solutions. How if I want to read points in 2D?

Hi Prasetyo,

Sorry but I don't really understand your question...what do you mean exactly by 2D? I am assuming we are always working in 2D since this is a profile, right?

[pedi_cfdonline]

I mean how to write the coordinate for 2D airfoil, is it something like this

# List of Point Coordinates
# Format is: integer Group, integer ID, X, Y, Z
# all delimited by spaces, with nothing after the Z value.
# Group 1
1 1 20.1234 25.4321 0
1 2 25.2468 30.1357 0
1 3 15.5555 16.6666 0
#Group 2
2 1 50.0101 100.2021 0
2 2 -22.3456 0.8765 0
2 3 21.1234 22.4321 0

many thanks

Yes Prasetyo. I think is that way.
