RustMann

A Mann turbulence generator for Python written in Rust. RustMann can generate 3D coherent turbulence boxes for wind turbine simulations as described in Mann, J. (1998). Wind field simulation. Probabilistic engineering mechanics, 13(4), 269-282.

Usage

RustMann separates the process of generating turbulence into two steps: stencil generation and turbulence generation. The stencil is a 5D matrix containing the spectral tensors needed to generate turbulence for a given set of parameters. A stencil can be reused to generate multiple random instances of turbulence. Implementations are provided in Python and Rust.

Python

import RustMann

params = {
    "L": 30.0,
    "gamma": 3.2,
    "Lx": 6000,
    "Ly": 200,
    "Lz": 200,
    "Nx": 8192,
    "Ny": 64,
    "Nz": 64,
}
ae = 0.2
seed = 1234

stencil = RustMann.Stencil(**params)
U, V, W = stencil.turbulence(ae, seed)

Rust

use RustMann::Stencil;

let (L, gamma) = (30.0, 3.2);
let (Lx, Ly, Lz) = (6000.0, 200.0, 200.0);
let (Nx, Ny, Nz) = (8192, 64, 64);
let ae = 0.2;
let seed = 1234;

let stencil = Stencil::from_params(L, gamma, Lx, Ly, Lz, Nx, Ny, Nz);
let (U, V, W) = stencil.turbulence(ae, seed);
