The Georgia Tech Tokamak Transport Code (GT3). Also known as GTEDGE2.

Installation

Using pip

$ pip install GT3

Installing from GitHub

• Master branch

Clone GT3 master branch from github

$ git clone https://github.com/gt-frc/gt3.git

• Other branches

You can clone another branch from github as follows:

$ git clone -b <branch> https://github.com/gt-frc/gt3.git

Installing Branches from GitHub via pip

To use pip to install a development version of GT3, simply use

$ pip install git+https://github.com/gt-frc/gt3@development

Neutrals Calculations

GT3 utilizes NeutPy (https://github.com/gt-frc/neutpy) for the calculation of neutral particles recycling from the wall. Neutpy is an optional dependency. NeutPy also requires the Triangle 2D meshing package (see the NeutPy github for details).

To install NeutPy:

$ pip install neutpy

Usage

GT3 can be run in 2 different ways: via a config file and profiles or via a test data class.

• From Files

The primary method of running GT3 is via the gt3 class

from GT3 import gt3

If neutpy is installed, you'll see a message indicating that it is being imported. Otherwise, a warning will be given. If you will be running neutpy, the main configuration file needs to be placed in the CWD. A sample configuration file can be found on the neutpy github as neutpy.conf

GT3 is instantiated in this manner by providing an input file.

myPlasma = gt3(inputFile="myInputFile")

See the /inputs directory for example input files (generally called togt3_d3d_shotid_timeid). The inputFile argument takes a file relative to the current working directory (CWD). An input file will include some plasma parameters and meshing information. In addition, the locations of 1D and 2D profile data are entered into this file. The locations also must be relative to the CWD. See the inputs directory for an example with DIII-D shot 144977.3000.

GT3 includes various modules that provide information and calculations about the plasma. Running gt3() with the mode argument will run different sets of modules (see gt3.py for a list of modes). Modules can also be run using the various arguments (run_IOL(), run_NBI(), run_radial_transport(), etc.).

To run the full radial transport code, use the mode='radialtrans' argument in gt3() or run myPlasma.run_radial_transport().
