Projects

A project is the central organising unit in FlowUrja Studio. It groups a turbine model, simulation input files, generated wind fields, and results under a single working directory on disk. Everything the app does — running TurbSim, launching OpenFAST, saving module settings — writes into that directory.

The welcome screen

When FlowUrja Studio launches with no open project, the welcome screen is shown.

Control	Action
+ New project	Create a new project in a chosen directory
Open project	Open an existing project folder
Recent	Re-open a recently used project directly
Continue without project →	Use the app without a project (limited functionality — module editors and batch tools require a project)

Creating a project

1. Click + New project.
2. In the dialog, choose or create an empty folder on your file system. This becomes the working directory.
3. Give the project a name.
4. Select a turbine model from the dropdown (see Models below).

FlowUrja Studio copies all required OpenFAST and TurbSim input files for the selected turbine into the working directory under a model/ subfolder. The project state is saved as project.json at the root of the working directory.

Opening an existing project

Click Open project and navigate to any folder that contains a project.json file. FlowUrja Studio restores the project name, turbine model, module settings, and the list of recent simulation runs.

The sidebar

Once a project is open, the sidebar provides access to all tools organised into five sections.

PROJECT

Shows the active project name and its working directory path. Click the project name to switch to a different project.

MODELS

Lists the turbine models associated with the project. A project can have multiple models — for example, comparing IEA 15MW Monopile and UMaine Semi configurations in the same working directory. Click + to add another model.

ENGINES

• OpenFAST — the aeroelastic simulation engine. The active .fst file is shown beneath the label. Click to open the OpenFAST panel.
• TurbSim — the turbulent wind field generator. Click to open the Wind Field panel.

MODULES

Lists the OpenFAST sub-modules enabled for the active model. Each module name is a shortcut to its editor panel. The coloured dot indicates status:

Colour	Meaning
Green	Module is enabled and configured
Orange	Module is enabled but has unsaved changes or a warning
(none)	Module is disabled in the .fst file

The OFFSHORE group (SeaState, HydroDyn, SubDyn, MoorDyn, IceDyn) is collapsed by default and expands when any offshore module is enabled.

BATCH

• Wind Field Batch — parametric TurbSim sweeps. See Wind Field Batch.
• Simulation Batch — multi-case OpenFAST runs. See Simulation Batch.

INSPECT

• Wind Field — visualise a generated .bts binary wind file.
• Results — load and analyse OpenFAST .outb output files.

Working directory structure

After creating a project and running a simulation, the working directory follows this layout:

my-project/
├── project.json          ← project state (name, model selection, settings)
├── model/
│   └── IEA-15-240-RWT-Monopile/
│       ├── IEA-15-240-RWT-Monopile.fst
│       ├── IEA-15-240-RWT_InflowFile.dat
│       ├── IEA-15-240-RWT_ElastoDyn.dat
│       └── ...           ← all OpenFAST sub-module files
├── wind/
│   └── ws12_A_IECKAI_s01.bts   ← generated TurbSim wind fields
└── results/
    ├── ws12_r001/
    │   ├── outb/
    │   │   └── ws12_r001.outb  ← OpenFAST binary output
    │   └── inp/
    │       └── ...             ← snapshot of input files used
    └── batch_sweep_01/
        └── ...

The model/ files are the live input files edited by the module panels. The results/ folder is where batch and single runs write their output.

Models

FlowUrja Studio ships with the following reference turbines:

Model	Rating	Configuration
NREL 5MW	5 MW	Onshore / fixed-bottom
IEA 10MW	10 MW	Onshore / fixed-bottom
IEA 15MW Monopile	15 MW	Offshore · fixed-bottom
IEA 15MW UMaine Semi	15 MW	Offshore · floating
IEA 15MW OLAF	15 MW	Fixed-bottom · free-wake aerodynamics
IEA 22MW Monopile	22 MW	Offshore · fixed-bottom
IEA 22MW Semi	22 MW	Offshore · floating

Custom turbines can be added by placing OpenFAST input files in a subfolder of model/ and opening the project — FlowUrja Studio will detect and list the .fst file automatically.
