This is an introduction on how to use Chrono::PyEngine, that is Chrono::Engine for Python.

The Chrono::PyEngine Python module is an alternative way of creating applications based on Chrono::Engine that does not require any C++ programming. In fact, once you installed the Chrono::Engine Python module in your Python environment, you will be able to use the easy Python scripting language to call a big part of the Chrono::Engine API functions, classes, methods, etc.

Advantages of Python programming vs. C++ programming:

  • Python is simple,
  • Python can be interpreted on the fly,
  • there are lot of third party modules for Python, for instance Matplotlib for plotting, Numpy for algebra, etc.,
  • a minimal installation is required.

Disadvantages of Python programming vs. C++ programming:

  • Python is slower than C++,
  • the Chrono::Engine Python module does not cover all the features of the C++ API.

The idea is that, once installed, you can open your Python IDE, import the ChronoEngine Python module(s) and start creating Chrono objects as in the following:

1 import ChronoEngine_python_core as chrono
3 my_systemA = chrono.ChSystem()
4 my_vect1 = chrono.ChVectorD()
5 ...

You can find more information on how to use Chrono::PyEngine in its reference page.
