Problem With Importing Coordinates for an Airfoil

Amerikaneca · October 22, 2010, 13:12

Hello everyone,

I have a .dat file with the coordinate points for a NACA4412 airfoil. I want to build the geometry, mesh it and analyze it with Fluent. However my first issue is that I cannot import the 500 or so coordinate points into Workbench Design Modeler. I keep looking online and I cannot find a direct answer to my question. Is it possible to import a .dat file into the DesignModeler so I can create the airfoil geometry? Short of that what do I need to do to import the coordinate points into the client? Can you give me any advice please? Thank you.

P.S. I figured it out, turns out it is quite easy. Select Point, Coordinate File, and make sure the coordinates are in a .txt file following the format:
Group Number Id Number X coord. Y coord. Z coord.
1 1 1 2 3
1 2 2 3 4
1 3 2 1 4

etc...
The help feature actually did help this time.

What does Group Number and Id number mean? in terms of design modeler that is

thank you

A little advice. I've understood DM demands the comma, not the dot in the .txt list.

this is correct answer:

In Ansys 12.1 I go to Concept menu and then select 3D curve. I then Import coordinates from .dat file in format mentioned in upper link
