Ansys/Flotran 3D Wing Analysis Help 2

[gkoz]

Right now I am working on a small-scale airplane, and I am trying to analyze the airflow around it by using ANSYS/Flotran. I have had some experience with Flotran on 2-D models, but the airplane wing is a 3-D design. There is nothing to find in the Ansys Tutorials or the Verification Manual. I want to calculate Lift, Drag, and Pressure coefficient on the wing.
I would like to guide me through the process of creating the air’s volume around the wing and how to mesh it. Do I have to apply an element for the wing also? Or do I have to subtract the wing’s geometry from the volume of the air around it and then mesh the volume that arises? I have already calculated the dimensions of the air-volume, and the exact position of the wing in it.
If you could, please make a simple example of a 3D wing analysis, basically including the air-volume generation progress and the meshing progress. Lets suppose that we need a plane’s speed of 12 meters/sec relatively near to the ground and the wings span is 1500 mm. Use of any airfoil, for the example.

If you have any questions (or answers) in this or a relative subject you can let me know.

Thank you in advance.

Dear rajasekaran
Thank you for your immediate response
I was wondering if you could post more information and details over this matter.
I have already began working on the 3D CFD analysis of the Wing using Flotran.
Which type of element could you propose for the wing? A very simple 3D flow analysis around a wing (or anything else) would be very helpful for me.
Thanks again
George.

Hi,
I'm currently trying to create a 3-D model of a wing in Ansys using flowtran. I have the same question as gkoz. If someone can post an example on how to create such model in ANSYS i would appreciate it very much.
Thanks
Tri
