The Heat flux Engineering Analysis Toolkit (HEAT) is a suite of tools for predicting the heat flux
incident upon PFCs in tokamaks, and the associated PFC state (ie temperature).
The toolkit connects CAD, FVM, MHD, Plasma Physics, Visualization, HPC, and more, in one streamlined package.
The objective is to enable engineers and physicists to quickly ascertain heat loads given specific magnetic
configurations and geometric configurations.
Some examples of what HEAT can predict:
- 3D heat loads from 2D plasmas for limited and diverted discharges
- Heat fluxes from the optical and ion gyro orbit approximations
- Time varying heat loads and temperature profiles
- Magnetic field line traces
- Many other quantities
The following physics modules are scheduled to be added to HEAT soon:
- Photon tracing, ie radiated power using CHERAB
- 3D plasmas using M3DC1
To cite HEAT, you can use a paper published by the journal Fusion Science and Technology under open access. The paper can be found here: https://doi.org/10.1080/15361055.2021.1951532
For users who want to run HEAT, there are two options:
- An appImage for running with a single executable on Linux
- A docker container, which also allows HEAT development
The appImage is available under the Releases tab on this github page. The docker container is available via docker hub. See the tutorials link below for more information on installation.
The developer is Tom Looby, a Postdoctoral Researcher at Oak Ridge National Laboratory. The project began during Tom's PhD.
This project is open source under the MIT license.

Below are a few examples of HEAT output. HEAT produces time varying 3D heat fluxes, and can easily create visualizations leveraging the power of ParaVIEW.
There is a HEAT presentation from Aug 2020 available here
