Wind turbine simulation,
made simplified.

FlowUrja Studio is a free, native desktop GUI for OpenFAST and TurbSim. Generate turbulent wind fields, run aeroelastic simulations, and analyse results — all without touching the command line.

Workflow

From wind field to results in one app.

A complete simulation workflow without switching tools or writing scripts.

1

Generate wind fields

Configure TurbSim parameters — wind speed, turbulence class, shear exponent, grid resolution — and generate IEC-compliant binary wind fields. Run batch sweeps across many conditions simultaneously.

Configure & run simulations

Set up OpenFAST with a guided module interface. Configure InflowWind, AeroDyn, ElastoDyn, ServoDyn, and offshore modules. Run single cases or launch a full simulation matrix in parallel.

Analyse results

Load OpenFAST .outb output files, plot time series and spectra, compare cases side-by-side, and export to CSV — without leaving the app.

Features

Run OpenFAST the right way.

Everything you need to go from wind field to results — ready out of the box, with fewer errors along the way.

Bundled Reference Turbines

Includes NREL 5 MW, IEA 10 MW, 15 MW, and 22 MW reference turbine models. Start a simulation in seconds — no manual file setup required.

Fewer Setup Errors

Structured input forms validate parameters before a run starts. Bundled binaries are version-matched — no PATH configuration, no compatibility issues between OpenFAST and TurbSim.

Native on macOS & Windows

A lean native binary with bundled OpenFAST and TurbSim. Nothing to install separately — just download and run.

Advanced Turbulence Parameters

Supports gradient turbulence intensity (gTI) — a vertical σu profile across the rotor disk for more realistic atmospheric boundary layers. Learn more →
