To do this, let's see how to use RocketPy's four main classes: - -- `Environment` - Keeps data related to weather. -- `Motor` - Subdivided into `SolidMotor`, `HybridMotor` and `LiquidMotor`. Keeps data related to rocket motors. -- `Rocket` - Keeps data related to a rocket. -- `Flight` - Runs the simulation and keeps the results. - -The following image shows how the four main classes interact with each other: - -![Diagram](https://raw.githubusercontent.com/RocketPy-Team/RocketPy/master/docs/static/Fluxogram-Page-2.svg) - -A typical workflow starts with importing these classes from RocketPy: - -```python -from rocketpy import Environment, Rocket, SolidMotor, Flight +git clone https://github.com//ActiveRocketPy.git +cd ActiveRocketPy +pip install -e . # install the ActiveRocketPy lib in editable mode +pip install -r requirements-optional.txt # install optional requirements +pip install -r requirements-tests.txt # install test/dev requirements ``` -An optional step is to import datetime, which is used to define the date of the simulation: - -```python -import datetime -``` - -Then create an Environment object. To learn more about it, you can use: - -```python -help(Environment) -``` - -A sample code is: - -```python -env = Environment( - latitude=32.990254, - longitude=-106.974998, - elevation=1400, -) - -tomorrow = datetime.date.today() + datetime.timedelta(days=1) - -env.set_date( - (tomorrow.year, tomorrow.month, tomorrow.day, 12), timezone="America/Denver" -) # Tomorrow's date in year, month, day, hour UTC format - -env.set_atmospheric_model(type='Forecast', file='GFS') -``` - -This can be followed up by starting a Solid Motor object.
