eqdsk 0.7.0

A reader, writer and converter for the eqdsk format

Eqdsk

An EQDSK reader and writer for GEQDSK (more soon), with COCOS identification and conversion.

There is support for writing an eqdsk to a JSON format (which is now preferred).

We have extended the EQDSK standard to optionally allow for the definition of a CoilSet.

Setup

We are pip installable therefore for the most recent release:

pip install eqdsk

or for the most recent commit

pip install git+https://github.com/Fusion-Power-Plant-Framework/eqdsk.git

For a developer setup please see CONTRIBUTING.md

Basic Usage

To read in an eqdsk (json or eqdsk) in its raw state:

from eqdsk import EQDSKInterface

EQDSKInterface.from_file('file.json', no_cocos=True)

To read in an eqdsk file with a known cocos format and convert it to a given cocos format:

EQDSKInterface.from_file('file.eqdsk', from_cocos=11, to_cocos=17)

Alternatively if the direction (clockwise or anticlockwise) and the units of phi (V.s or V.s/rad) are known, the cocos standard will be calculated for you:

EQDSKInterface.from_file('file.eqdsk', clockwise_phi=True, volt_seconds_per_radian=True)

CLI

This package includes a CLI tool for eqdsk exploration.

This can be accessed by running eqdsk in the terminal after installing the package (or in the Hatch cli environment, see CONTRIBUTING.md).

For more information on the CLI tool, run eqdsk --help.
