[yt-users] YT-3.3.1 : selecting cells in a sphere

[Vincent Picouet]

Hi,

I am getting an issue with a very basic YT code:

I am using the 3.3.1 version and I can not access the cells contained in a sphere (it returns all the cells of the ENZO simulation):
The YT cookbook explains that to access the different fields (for example the x position) of the cells contained in a sphere one must code : ds.sphere[(0.5,0.5,0.5),0.1)][‘x’] …
But it gives me exactly the same results of ds.all_data().[‘x’] which is a 100M cells’ list.
Do you have an idea about selecting only the sphere region easily?

Thanks

Vincent
