☕ CappuSim v0.2.0 - Beta

CappuSim is a fast, modular and extensible Lattice Boltzmann Method (LBM) simulator built with Rust + OpenCL.

This beta release lays the foundation for a high-performance, GPU-accelerated solver, designed to be both educational and efficient. It provides a platform for experimentation and research of fluid dynamics.

Updates in v0.2-beta

  • Improved overall performance
  • Bug fixes
  • Validated against classical CFD scenarios (will be released soon)

✨ Features in Beta

  • 🔬 LBM Core Solver

    • Supports D2Q9, D3Q7, D3Q15, D3Q19, D3Q27 models
    • Streaming + collision (BGK)
    • Modular flags: FLUID, SOLID, EQ

  • 🌊 Simulation Examples

    • Taylor–Green Vortex
    • Poiseuille Flow
    • Lid-Driven Cavity
    • Von Kármán Vortex Street
    • Splash
    • Lid-driven Cavity
    • Airfoil

  • 📤 Output Formats

    • .csv
    • .vtk for visualization in ParaView
    • Exports: velocity, density (vorticity, Q-criterion are currently disabled)

  • 🧪 Benchmark Ready

    • Standard Benchmark example
    • MLUPs calculation
    • Scalable to large 3D grids

📁 Project Layout

  • /src/core/ – OpenCL kernels + LBM engine
  • /docs/ – LBM theory and usage (in progress)
  • /output/ – simulation results

🚀 Getting Started

git clone https://github.com/gustavoverneck/CappuSim
cd CappuSim
cargo build --release
cargo run --release

⚠️ Notes

  • This is a beta release — experimental, under development.
  • Currently tested with OpenCL 1.2+ on NVIDIA/AMD GPUs.
  • Focused on correctness, modularity, and ease of experimentation.

🛣️ Roadmap (no promises)

  • Formal validation
  • Temperature
  • Forces (will be released on next version)
  • (Maybe) Graphical interface
  • Multiphase fluid
  • 3D solids input
  • Plasma extension
