Hi everyone,

when I import the coordinates of my airfoil (points, curves, and surfaces) the leading edge get somewhat sharp and doesn't pass over the points exactly when closing it up.

I imported the points only and drew the leading edge manually, it became smoother, but is very expensive in time consumed.

how can I get my airfoil smooth and accurate without hitting each point to draw it manually?

thanks in advance,

How many curves are you importing? To get the smoothest curve you should import only 1 curve, say you import 80 points and 80 curves you're just going to get a bunch of straightlines. the more points per curves the smoother the curve.
I hope this helps.

thank you Matt, for your reply.

for one run, I have one airfoil with two curves (upper and lower surface), 90 points each.
but I have about 30 airfoils.
actually, I imported the coordinates file as points without curves, then drew the two curves by hitting each point. the leading edge get smoother.
Besides, I used the reply script to repeat these steps for the other airfoils.
but I am asking if there is another more modern way for more complicated applications.

I see, it's funny I'm actually doing something very similar but instead of importing the points (because every airfoil has a different number of reference points) I only import the curve into a template file I've created that contains the far field and then I run a replay script that adds about 160 points to the curve and then does all the geometry, associating and meshing for me. Once the script is done I just double check the mesh and save. It saves so much time.
