## What it is
OpenFOAM-dev is the development repository of OpenFOAM, a free, open-source C++ toolkit for computational fluid dynamics (CFD) maintained by the OpenFOAM Foundation. It provides solvers and libraries for simulating fluid flow, heat transfer, thermodynamics, chemistry, and related physics, with weekly-packaged development builds that may break backward compatibility.

## Use cases
- simulate fluid flow and aerodynamics around products
- model heat transfer in solids and fluids
- run combustion and reacting-flow chemistry simulations
- develop custom CFD solvers and boundary conditions in C++
- replace expensive proprietary CFD licenses with open-source tooling
- perform safety and troubleshooting calculations for engineering designs
- test upcoming OpenFOAM features before stable releases

## When to choose
- you need a free, extensible CFD platform with full source access
- you want to contribute to or track the latest OpenFOAM features
- you build custom solvers on top of OpenFOAM's C++ libraries
- you need industrial-grade CFD for research, design, or safety analysis

## When to avoid
- you need a stable, backward-compatible release for production (use OpenFOAM-14 instead)
- you want a turnkey GUI-driven CFD application with minimal setup
- your team cannot maintain builds from a development line that may break compatibility

## Facets
- artifact type: library
- maturity: active
- function: simulation, developer-tools
- domain: simulation
- platform: windows, cpp
- tags: cfd, computational-fluid-dynamics, finite-volume, solver, physics, engineering, numerical-methods, heat-transfer, thermodynamics, mesh-generation, scientific-computing, linux, macos
