yt-idefix 0.7.0

An extension module for yt, adding a frontend for Idefix

yt_idefix

A maturing yt frontend for Idefix, 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

Single dump files as well as time series can be loaded directly with yt.load, e.g.,

ds = yt.load("dump.0054.dmp")
ts = yt.load("dump.00??.dmp")

For vtk files, with yt < 4.0.2, a specialized loader function is provided

ds = yt_idefix.load("data.0042.vtk")

With yt >= 4.0.2 (not released yet), this workaround will not be necessary and yt.load will be usable directly.

Strecthed grids support

yt_idefix comes a specialized loader function for datasets with streched grids yt_idefix.load_stretched. This function is experimental. Here are its known limitations.

• 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)
