Help regarding importing 2 element aerofoil and meshing.

hop04 · February 13, 2025, 16:56

Hey, I have two questions.

1) I understand that if I want to import aerofoil geometry into Pointwise, for a normal 1 element aerofoil, I would just import the ASCII coordinates from a website such as

http://airfoiltools.com/airfoil/deta...l=naca23012-il

However I am not sure what format the textfile must be?

2) I am trying to import the following 2 element aerofoil.

https://ibb.co/LhpkMpCg

It is a N.A.C.A. 23012 AIRFOIL WITH AN N.A.C.A. 23012 EXTERNAL-AIRFOIL FLAP.

How would I go about importing such a mesh in Pointwise Fidelity. Is there a way in Pointwise for me to import two aerofoils (in this case it would be importing the 23012 datafile twice) and then, by using some transform tool, I can translate, scale and rotate the flap. Is this possible? Or is there a way to produce this aerofoil in some software and get its coordinates.

3) I will be analysing the lift of this foil, would it be best to use an extrusion-normal O-type topology? That seems simplest.
