Question: I have a simple setup.

An active cube and a passive plane with rigid body physics activated.
An empty with wind physics activated and the strengh set to 1000.

When I play the animation, nothing happen except for the cube falling on the plane...

Did I miss something ?

Answer: 
First of all you need to select the inner ring that you created with `I`. You can use `Alt` for it. Then deselect everything that is fine with the circle selection tool (`C`). Then press `X` and select Edge Collapse. Your problems should now be fixed. For that selection part I made a little picture here:

Just deselect everything which is outside the problem area.
You need to merge the faces at this point in your model. Select two faces and them press Alt-M. Select "To Center".

As answered before in the link below.
