## What it is
CFD Python is a series of Jupyter notebooks ('12 Steps to Navier-Stokes') that teach the foundations of Computational Fluid Dynamics by coding solutions to the governing PDEs of fluid flow. Created by Prof. Lorena Barba, it is designed for self-study or as course material, requiring only basic programming and some PDE background.

## Use cases
- learn computational fluid dynamics from scratch
- self-study numerical solutions to Navier-Stokes equations
- teach a university CFD course with hands-on notebooks
- practice Python and NumPy through physics simulations
- understand numerical diffusion, accuracy, and convergence
- prepare for CFD research with foundational exercises

## When to choose
- you want a step-by-step, incremental introduction to CFD
- you prefer learning by writing code rather than reading theory
- you need free, citable course material for fluid dynamics
- you have basic Python knowledge and PDE background

## When to avoid
- you need production CFD simulation software
- you want a GUI-based fluid dynamics tool
- you have no interest in programming the solutions yourself

## Facets
- artifact type: learning-resource
- maturity: stable
- function: simulation, data-visualization
- domain: simulation, education, tutorials
- platform: python, cross-platform
- tags: computational-fluid-dynamics, jupyter-notebooks, navier-stokes, numerical-methods, self-study, education
