Vatpy (Visualisation of Arepo in the Terminal using PYthon) is a light-weight, highly customisable, visualisation tool-kit for astrophysical simulations performed using the Arepo code (Springel 2010). Many of its functionalities can be generally applied to simulations made by Arepo (as long as the output is in HDF5-format), however, more specific capabilities, such as creating visual maps of the gas chemistry, is at the moment only adapted to simulations run using the ArepoNoctua numerical framework (Petersson et al. 2025).
Please see the dedicated user guide on the official Vatpy Docs page: https://vatpy-code.github.io/vatpy, for detailed instructions on how to install and use Vatpy for your work.
