FUSE.jl

FUSE (FUsion Synthesis Engine) is an open-source framework for the integrated design of Fusion Power Plants (FPP). Originally developed by General Atomics, FUSE is now publicly available under the Apache 2.0 license.

Resources

Here are some key resources for getting started with FUSE:

Objectives

FUSE aims to achieve the following objectives:

⚡ Provide a highly efficient, modular framework that tightly couples models across different domains.
🧩 Integrate plasma physics, engineering, control, balance of plant, and costing systems.
🤖 Leverage machine learning to overcome the typical fidelity/speed tradeoff in simulations.
⏱️ Support both stationary and time-dependent simulations.
💻 Harness parallelism and high-performance computing (HPC) for large-scale studies.
🎯 Perform multi-objective constrained optimization to explore design tradeoffs.
🔍 Enable comprehensive sensitivity analysis and uncertainty quantification.

Basic Concepts

FUSE is entirely written in Julia and is structured around the following core concepts:

📂 Data storage: All data is stored in the dd structure, which follows the ITER IMAS ontology.
🧠 Actors: The core components of FUSE simulations are physics and engineering actors.
🕹️ Control: Actor functionality is governed by act parameters.
🚀 Initialization: The data structure can be initialized from 0D ini parameters.
🔧 Use cases: FUSE includes templates for various machines (e.g., FPP, ITER, ARC).
🔄 Workflows: Self-contained studies and optimizations are conducted via workflows, typically involving multiple FUSE simulations.
🌍 Interoperability: FUSE interfaces with existing modeling tools like OMFIT/OMAS and the IMAS ecosystem.

A diagram illustrating these concepts is provided below: FUSE Diagram

Usage Example

Here’s a simple example of setting up and running a FUSE simulation in Julia:

using FUSE

# Obtain `ini` and `act` parameters for a specific use case
ini, act = FUSE.case_parameters(:FPP)

# Initialize the `dd` structure from 0D `ini` parameters
dd = FUSE.init(ini, act)

# Run a stationary plasma actor simulation
FUSE.ActorStationaryPlasma(dd, act)

# Get an overview of the simulation results
FUSE.digest(dd)
