Its all relative
Maybe someone else will have a good idea, but the way I see it, wind speed is all relative.
If you want to say that the blade is moving in a certain direction, you can do that with a 2D model by...

Those steps look fine... But you need to check again if you have anything but Shells in your fluid part...
Turn off all your parts.
Turn on your Fluid Part.
Turn on points, fit to screen to...

One or the other.
A model is composed of a fluid surrounded by boundary conditions...
In your model, the volume and the shells (or the the shells and the lines if 2D) are in the same part. The solver can't...

Not the right file...
Samia,
The *.prj files are not enough.
The *.tin file is the geometry and mesh parameters. (I need this)
The *.blk file is the blocking (This would be nice if you have taken a first try)

1) There are several tutorials that will train you toward this goal... Basically, you would do what I did in 2D, but start with a 3D block and do everything on both faces... Or start with a 2D...

Oh, just simple 2D airfoil...
Sorry, I got carried away... If you just want to model the 2D profile of one blade, then you just model that... You can do it just like my Youtube movie...

More similar than different
You could do the exact same as Etesh, except one of your 2D boundaries becomes the ground. Then extrude it by the length of your cylinder to get it to 3D.
Sounds like an odd design though, how...

3 suggestions...
You adapted it well to your situation (OGrid instead of a CGRID).
In the end, you have a very orthogonal mesh at the trailing edge... Depending on your solver, it may be better to relax the...

How to delete line elements

I think I get your question now. You were copying the mesh before going to Fluent and then needed to get rid of those sides that end up...

They are on the ANSYS...

Not right at all...
I might come back to look at your file later (perhaps someone else has time to help?)
I thought you wanted to have three airfoils all orbiting a central point? In which case you could mesh just...

Right...
Right, so it is just like meshing a regular static domain, except that it is in a circle... Then the entire circle is set to rotate. The surrounding mesh has the equivalent circle cut out of it,...

Dynamic what?
The meshing is no problem...
But the mesh would just be a static mesh...
By dynamic, do you mean that the flow is dynamic around a static airfoil or do you mean that the flow causes the airfoil...
