[FLASH-USERS] Visualizing 3D Cylindrical grid

[Rahul Kashyap]

Hi Nathan,

Thanks. I think that was the problem. I was annotating grids. I have yt
3.3.2; most recent is 3.3.3.

Is it possible to do so now for cylindrical grids? It might be required for
my analysis at some point so, may be you could point me towards tweaking yt
to get it working.

Best,
-Rahul


%matplotlib inline
import yt

path='super3d_hdf5_chk_0000'
ds = yt.load(path)

s = yt.SlicePlot(ds, "r", ["density","temperature"], center=[0,0,0])
s.zoom(20.0)
#s.annotate_grids()
s.show()
s.save('temp_data/')
#"""
