Hi

I'm trying to create an O-grid in a 2-D geometry. I've completed the 2-D car tutorial. However, I'm still unable to create the required mesh. I've attached a picture of the geometry and a primitive mesh. Essentially what I want to do is create a grid such that I have concentric semi-circles from the semi-circular notch in the geometry.

I suspect it's something to do with selecting the blocks, but I've tried everything I can think of.

Thanks.
