but remain unsure of where to find the relevant source code/what I do with it after I find it. Matt explained that yt/frontends/sph/data_structures.py is "where the data frontend is. The broader yt codebase uses that to index and manage the data but it uses generic interfaces on top," and encouraged me to email the list for more information. Where is the relevant code? Also, where does the generic vs. frontend interface distinction appear?
Best,
