Overview

BondGraphTools is a python library for systems modelling based on the bond graph methodology [Gaw1996], [Gaw2007].

BondGraphTools is intended to be used by:

• software developers; as a framework to build modelling interfaces on top of
• engineers; to quickly build and simulate physical systems
• mathematicians; to perform model reduction and analysis

BondGraphTools is built upon the scientific python stack; numpy, scipy, sympy and matplotlib, and relies on Julia and DifferentialEquations.jl to handle numnerical simulation.

How to read the docs

The documentation for this library is organised into five sections.

• This page show how to install BondGraphTools
• Tutorials contains a list of step-by-step tutorials demonstrating how to use BondGraphTools.
• How-To Guides contains recipes for common tasks.
• Discussion contains high level discussion about to library.
• API Reference is the library reference documentation.

Getting Started

Requirements

• Python 3.6 or above.
• Julia 0.6. Note: Julia 0.7 and above are not yet supported

Installation

1. Install Julia 0.6.4 which can be downloaded from here.
2. Make sure Julia 0.6.4 is in your path variables. You can test this by typing julia -v at the command prompt. If this returns julia version 0.6.4 then julia is in your path variables.
3. Install BondGraphTools via pip: pip install BondGraphTools

BondGraphTools is now installed and will download and install the required julia packages the first time you import it.

Usage

BondGraphTools can be loaded inside a jupyter-notebook, python interpreter, or script by using:

import BondGraphTools

Users need an internet connection during the first load as the it will download the required packages from the julia package repository.

Api reference for the package and it’s contents can be accessed using the help command:

help(BondGraphTools)
