Meshing for a 2D case
 

Hi...I am facing problem with meshing as im a new user to Ansys. Till now, I have only drawn the geometry and I have no idea about how to mesh. I have tried the tutorial(2D car), and I am aware that I must do blocking for this. But in my case, where I have to mesh the flow around the rotor, i think blocking is not a convenient way as the blades are very small, compared to a car. So, i was thinking that there may be some other way and hope that someone can guide me in the right path. tq

(The geometry consist of a box which represent the wind tunnel and the rotor in the middle of it.) Plz refer to the picture attached.

If i am right you can try it this way.

Create one more box around the motor. Subtract the motor from the inner box.Make equal number of divisions on all the of the inner box and the outer box and try to mesh it with quad.
Then the inner portion of the inner box you can mesh with tri. The inner surface of the rotor will automatically get meshed.

Hope that will help.
your problem was not well elaborated to me.

Thanks
