User Guide

The User Guide describes how to configure and use FLINT in practical applications.

• Using the Library

  ---

  How to use FLINT API.

  Embed FLINT in your code

• Input Format

  ---

  How to define thermodynamic data, chemistry, and simulation parameters. Includes YAML and native formats.

  Configure input files

• Chemistry Database

  ---

  Available mechanisms and how to extend FLINT with new dedicated routines.

  Explore mechanisms

This section is intended for:

• Developers embedding FLINT in a CFD or reacting-flow solver
• Users configuring thermodynamic and chemical mechanisms
• Engineers running simulations with dedicated or general chemistry routines

If you are new to FLINT, start from Getting Started.

Scope of This Section

The User Guide covers:

• API basics for all features
• Input formats (YAML and native)
• Available chemical mechanisms and how to generate optimized mechanism-specific routines

It does not describe:

• The mathematical background (see Theoretical Guide)
• Internal architecture (see Developer Guide)
