Welcome to my Research Blog.
This is mostly meant to document what I am working on for myself, and to communicate with my colleagues. It is likely filled with errors!

1024 Sims Catalogs
AHF is crashing while trying to read in the snapshot files. Not sure why.
The error message is:
FATAL: No clue what kind of floating point uses 0 bytes. Aborting reading.
FATAL: Expected to read 0 particle positions, but only got 4512357996. Aborting.
Check Snapshot
I checked that the final snapshot looks okay:
Here is the snapshot at the \(512^3\) resolution
And with \(1024^3\) particles:
The snapshot looks great, so it seems that the simulation ran fine.
However, I wasn’t able to read in the 1024 snapshot with yt or pynbody (though I could read in the 512 snapshot). So I think there is something different about how the snapshot is formatted… I was able to read it in fine with my own code though, so I am not sure what is different. I need to look into this further, and maybe change the function in AHF that reads in the GADGET files.
I looked through the code, and realized that you can add the line #define AHOBBS_GADGET_FILE_FIX to define.h, and it fixes the problem
