This is the python/rust flavor of NREL's FASTSimTM, which is based on the original Excel implementation. Effort will be made to keep the core methodology between this software and the Excel flavor in line with one another.
All classes and methods are self-documented.
Set up and activate a python environment (compatible with Python 3.8 - 3.10; we recommend Python 3.10) with the following steps.
- Create:
conda create -n fastsim python=3.10 - Activate:
conda activate fastsim
There is some variation based on your Operating System:
-
PowerShell (windows):
- Create:
python -m venv fastsim-venv-- name is user decision - Activate:
fastsim-venv/Scripts/Activate.ps1
- Create:
-
Bash (i.e. unix/linux/mac):
- Create:
python -m venv fastsim-venv-- name is user decision - Activate:
source fastsim-venv/bin/activate
- Create:
-
Command Prompt (windows):
- Create:
python -m venv fastsim-venv-- name is user decision - Activate:
fastsim-venv/Scripts/activate.bat
- Create:
In an active Python environment created above, run pip install fastsim.
Developers might want to install the code in place so that FASTSim files can be editable (the -e flag for pip provides this behavior). This option can be handy since FASTSim will be installed in place from the installation location and any updates will be propagated each time FASTSim is freshly imported. To do this, you'll need to have the Rust toolchain installed.
- Option 1: run
sh build_and_test.shin root folder. - Option 2:
- Run
pip install -e ".[dev]"
Optional testing steps: - Run
cd rust/ && cargo test - Run
pytest -v python/fastsim/tests/
- Run
To see and run examples, download the FASTSim demo files using the following code (with your Python environment activated and FASTSim installed):
from fastsim import utils
utils.copy_demo_files()This code downloads demo files into a specified local directory (if no directory is specified, it will create a \demos folder in the current working directory). WARNING: If you download the demo files to a location where files of the same name already exist, the original files will be overwritten.
Add this line:
fastsim-core = { git = "https://github.com/NREL/fastsim/", branch = "fastsim-2" }
to your Cargo.toml file, modifying the branch key as appropriate.
FASTSim is available as a Rust crate, which can be added to your dependencies via the following command:
cargo add fastsim-core
