Mann.rs¶

Mann.rs is a high-performance turbulent wind field generator based on the Mann turbulence model, designed for wind turbine and wind farm simulations. It produces three-dimensional coherent wind fields and supports both unconstrained and constrained turbulence generation.

Built in Rust for speed and efficiency, Mann.rs provides seamless Python bindings and a command-line interface for easy integration and scalability into engineering workflows.

Installation¶

Mann.rs is available for Windows, MacOS, and Linux as a Python package.

pip install mannrs

For more details on the installation process, see the installation Guide.

Usage¶

Command line¶

mannrs input.toml

Define your simulation parameters in a TOML file. See the Input file format for details.

Python¶

from mannrs import Stencil

...

(
    Stencil(**mann_params)    # Define a stencil with Mann parameters
    .constrain(constraints)   # Apply velocity constraints (optional)
    .build()                  # Build the turbulence stencil
    .turbulence(ae, seed)     # Generate turbulent wind field
    .write("out.npz")         # Save windfield to file
)
