[yt-users] Is there a way to interpolate GADGET images?

[Desika Narayanan]

Hi Joseph,

It's not an exact answer to what you're looking for but one thing you can
do to help is force an over refining in the octree building (i.e. each
'False' in the octree will still have 8 child cells instead of being the
terminal point in the refinement).   So, based on the above notebook, you
could load doing something like:

>ds = yt.load(fname,unit_base=unit_base,bounding_box = bbox,
over_refine_factor = 1)

and you can increase over_refine_factor accordingly beyond 1 of course too.
 (The default is 0).  Note though that it can get very taxing on the memory
to go even beyond over_refine_factor=2.
