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....

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.
