GadgetIO.jl

This package provides IO functionality to work with the Smoothed-Particle Hydrodynamics code Gadget by Volker Springel.

It is taylored for working with the development version of P-Gadget3, specifically OpenGadget3 developed by Klaus Dolag and contributers. Development is focused on IO for Binary Format 2. A lot of the routines are based on IDL scripts by Klaus Dolag (not public).
