yt-idefix 0.13.1

An extension module for yt, adding a frontend for Idefix

yt_idefix

A maturing yt frontend for Idefix and Pluto (vtk), packaged as an extension for yt. This frontend is a candidate for integration in the core yt code base.

Installation

pip install yt_idefix

Usage

After importing yt itself, make sure to activate the extension

import yt
import yt_idefix

Now yt.load will be able to read Pluto/Idefix .vtk output files, as well as Idefix .dmp dump files.

Strecthed grids support

yt_idefix 0.12.0 and newer

version 0.12.0 brings experimental native support for streched grids, which is under active development upstream, in yt itself.

Slices should now work seamlessly even with older versions of yt, however yt 4.1 (to be released) will be required to perform projections correctly.

In the meantime, I recommend installing yt from source. At the time of writing, the branch attached to the following pull request is required for projections with stretched grids:

yt_idefix 0.11 and older (deprecated)

yt_idefix ships a specialized loader function for datasets with streched grids yt_idefix.load_stretched. This function is only provided as a workaround 4.0.x limitations, but it's highly limited itself:

• no field magic (no aliasing, or dimensionalization, or automatic derived field generation)
• no lazy loading (all data has to reside in memory)
• projections are not supported
• only supports vtk outputs (not dumps)
