I would also love to have Enzo-P supported in yt! I'm not very experienced with either using or developing yt (yet), but I'm willing to spend some time on it. If I remember correctly, the structure of Enzo-P output is currently not very efficient for yt, especially for larger datasets, so I expect some modifications to Enzo-P/Cello output may also be helpful. I do have other more urgent stuff I need to finish first, but hopefully I can start working on this soon. Thanks, James On Thu, Sep 1, 2016 at 4:04 PM, Nathan Goldbaum wrote:

Hi Thomas,

yt doesn't currently support loading data from Cello without doing some preprocessing work first. If the data fit in memory, you should be able to load the data with the load_amr_grids(), which supports loading arbitrary AMR data. Here's the documentation for load_amr_grids:

http://yt-project.org/docs/dev/reference/api/generated/yt. frontends.stream.data_structures.load_amr_grids.html http://yt-project.org/docs/dev/examining/generic_array_data. html?highlight=load_amr_grids

I know that Matt Turk experimented with loading Enzo-P/Cello about at the last Enzo workshop in 2015. Here's a script from my e-mail archives from back then that purports to load some cello data (no idea if something analogous will work with your data):

https://paste.yt-project.org/show/5880/

I never tried running this script, so no warranties or guarantees :)

In principle it should be possible to write a code frontend for Cello/Enzo-P and support it as a first class level in yt, but someone would need to spend time working on that.

If you or anyone else would be interested in adding an Enzo-P/Cello code frontend, I'm sure it would be a very welcome addition that we would love to have as part of yt. There are several people who have been working on adding new frontends for other codes recently so you should be able to get some freshly informed advice.

Greetings yt users,

My name is Thomas and I am currently working with the new AMR code * Enzo-P / Cello* being developed by James Bordner. I would love to be able to analyze the data using yt, but Cello is not currently supported in any version of yt I have found. I would greatly appreciate any help with adding a Cello frontend to yt. I have uploaded a data output (~140 MB) from a recent version of Cello to my dropbox here: https://www.dropbox.com/ s/ysjgnnw9tcbiu6h/sedov-cello.tar.gz?dl=0 . Thank you,

-Thomas Bolden
