I am totally new to CFX. I am trying to simulate NACA 0012 with CFX. As the first step, I am trying to import the coordinates of NACA 0012 to DesignModeler in order to make the geometry. Can anybody help me about the format of the file and how I can import it?
Thank you very much.

this is the sample file format I copied from CFX help:

#------------------------------------------------------------
# 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 30.5678
1 2 25.2468 30.1357 35.1928
1 3 15.5555 16.6666 17.7777
#Group 2
2 1 50.0101 100.2021 7.1515
2 2 -22.3456 .8765 -.9876
2 3 21.1234 22.4321 23.5678
#------------------------------------------------------------

make a text file with above format, then to import into design modeller,goto [Create] menu -> Point
and select the file you've just created.

Hello, I am a newbie. I am also trying to insert coordinates of Selig 1223 RTL, eppeler, etc. though the above comments are useful, I would just like to clarify one thing. Is the grouping of the coords based upon lower surface and the upper surface ?

Thanks for any help !

Dude, maybe you need some info about Excel?

manual input, of so many points is not that good idea.

u can exprot files from excel!!! to .txt extention

Hi,

I would like to know whether Ansys is able to support exponetial format.

As in my text file, i specified it to be %g.

Because my data value is too small, if i use %f, it will truncate to 0.

Best Regards,
natur3

I am doing a similar thing, importing coordinates and I can do that just fine, but how can I use these new points in a sketch? they seem completely separated and cannot be snapped to with lines. I can construct lines from points but i cant select those lines inside a sketch either.

Hi all,

I cannot manage to import the .txt file, with the format given above, in order to insert some points...

I am working with Ansys version 13.0. I can go to Ansys Main Menu > Preprocessor > Modelling > Create > Keypoints (?) > ..?.. Then I can't find the right window to browse and import my file.

Also tried to import the text file via File > Read input from ... But this didn't work either.

Can someone help me? Many thanks!

I successfully imported the coordinates of NACA 0012.

I need to import the coordinates of airfoil with some extrusion or protuberance. actually i want to import the coordinates of airfoil with gurney flap.
Do I have to change the group of the points in .txt file or something else??

Kindly help

to generate txt file from excel, save the excel file as ".txt (tab delimited)" format to import the geometry into ansys.
u will need specific format of coordinates depending upon whether u are creating ur geomtery in Design Modeler or in ICEM CFD

Hi Guys,
I am learning ansys DM, I have a fan coordinate points and modified it according to ansys text format, then

create --> points --> .txt file which I created, I am able to see the points in DM.

When I try to connect the points using spline, I couldn’t find the spline option in the sketch tap.

how to get spline in DM or is there any other option?

Thanks,
Sivakumar

Sorry for the post I got it,

it is under concept --> 3Dcurve (select Point select as definition) then select the points.

Thanks,

I was successful in importing the co-ordinates of naca0015, as mentioned in this post. I created a 3D curve out of it. In the part, bodies it shows line body. When I click on it, it shows that the cross-section is not defined. May I know how to define this?

Another thing, I want to analyse flow over this airfoil in 2D. So, I need to create a rectangular domain over it. Then, I need to subtract the airfoil from this domain. However, the boolean option does not select this line body as the tool body. Also, I am not able to create a surface from this curve. How should I go about it?

@dreamz:
make sure ur line body is making a closed curve.
surface can only be generated by closed curve. then apply boolean

and for 0015... is zero camber airfoil so i think C-type domain (instead of rectangular domain) can also be good and easy for u

@shubham

Please see the attachment. in the last line i had put

1 0 as mentioned in one of the post on this fourm.Import of 3D-curve from .txt


I could not create a surface from the 3D curve.

first of all.. try to get more points..they are just 35 points.
try to get atleast 100 points from some online airfoil generator.

second, yes, u need to put 1 0 in last point, to make a closed curve.

try this attached file and check what is the difference in your file and mine, and let me know!!!
