GadgetIO.jl

This package is a subproject of GadJet.jl and provides some basic IO functionality to work with the SPH code "Gadget" by Volker Springel (doi:10.1111/j.1365-2966.2005.09655.x).

Any help and contribution is greatly appreciated, as this is still a work in progress.

Quickstart

Reading Data

If you want to read a simulation snapshot into memory with GadJet.jl, it's as easy as this:

    data = read_snap(filename)

This will return a dictionary with the header information in data["Header"] and the blocks sorted by particle type.

As an example, this is how you would access the positions of the gas particles:

    data["Parttype0"]["POS"]

If you only want to read a specific block for a single particle type (e.g. positions of gas particles) you can use the function with a specified blockname and particle type like so:

    pos = read_snap(filename, "POS", 0)

This will return an array of the datatype of your simulation, usually Float32.
