cfd-vv-suite — CFD Verification & Validation Suite
An open test suite for verification and validation (V&V) of computational fluid dynamics codes. 51 cases: 1D/2D/3D, laminar/turbulent, Newtonian/non-Newtonian, stationary/moving bodies.
Overview
cfd-vv-suite provides a standardized, reproducible, solver-agnostic toolkit for testing CFD solver accuracy. It works with any solver (OpenFOAM, SU2, Fluent, custom code) — the user provides simulation results as CSV and the CLI tool compares them against reference data, computes error norms, and generates reports.
Quick Start
Installation
# From PyPI (recommended — no clone needed, all cases included)
pip install cfdvv
# Or from source (for development)
git clone https://github.com/vvp-cfd/cfd-vv-suite.git
cd cfd-vv-suite
pip install -e tools/
# Docker images
docker pull vvpcfd/cfdvv # Docker Hub
docker pull ghcr.io/vvp-cfd/cfd-vv-suite # GitHub Container Registry
Usage
# List available cases
cfdvv list
cfdvv list -c validation
# Compare your results against reference
cfdvv compare poiseuille-2d \
--result my_results.csv --norm L2 --plot
# OpenFOAM: ready-to-run Poiseuille case (from cloned repo)
cd cases/verification/incompressible/poiseuille-2d/openfoam && ./Allrun
# Generate analytical solution on a given mesh
python cases/verification/incompressible/poiseuille-2d/scripts/generate_solution.py 10 20 my.csv
# See expected output format
cfdvv example-output poiseuille-2d
# Run all verification self-tests
cfdvv benchmark
# Generate HTML report
cfdvv report poiseuille-2d \
--result my_results.csv -o report.html

OpenFOAM Integration
Verification cases include ready-to-run OpenFOAM setups. You need OpenFOAM 11+ installed.
Option 1: Native OpenFOAM
pip install cfdvv # or pip install -e tools/ from the cloned repo
cd cases/verification/incompressible/poiseuille-2d/openfoam
./Allrun
Option 2: Using our Docker image
Pull the pre-built image from either registry:
docker pull vvpcfd/cfdvv-openfoam # Docker Hub
docker pull ghcr.io/vvp-cfd/cfd-vv-suite-openfoam # GitHub Container Registry
docker run --rm -v $(pwd)/cases:/cases vvpcfd/cfdvv-openfoam

External Sources — cfdvv import
Beyond the 51 built-in cases, cfd-vv-suite connects to external V&V databases:
cfdvv import --list # 35 external cases from 6 sources
cfdvv import flatplate # auto-detects source, downloads data
cfdvv import flatplate -r my.csv --plot # import + compare in one step
