twobodyproblem 2.0.0

a little simulation for the gravitational two body problem

Two Body Problem

a small simulation

Welcome!

I wrote a small program in Python to simulate the two body problem. You type in some parameters, like mass, radius, velocity and distance. The program will show you a visualization of the simulation.

This program is command line only. If you want a graphical user interface, visit this GitHub page.

Installation Instructions

(You may need Microsoft Visual C++ to be able to run the program, so install it from here if needed.)

via PyPi

The Python package manager pip will install the last uploaded version from the Python Package Index PyPi. This will not always be the latest version, so if you want to install all the latest features, install it from GitHub (see below).

1. Make sure Python and pip are installed correctly.
2. Run these commands from a command line:
   1. pip3 install --upgrade pip setuptools wheel
   2. pip3 install --upgrade twobodyproblem
3. Now, the program is runnable with python -m twobodyproblem or python3 -m twobodyproblem.

via GitHub

1. Make sure Python and pip are installed correctly.
2. Make sure Git SCM is installed correctly.
3. Run these commands from a command line:
   1. mkdir TwoBody and cd TwoBody
   2. git clone https://github.com/Two-Body-Problem/twobodyproblem-simulation-python.git
   3. pip3 install --upgrade pip setuptools wheel
   4. pip3 install twobodyproblem-simulation-python
4. Now, the program is runnable with python -m twobodyproblem or python3 -m twobodyproblem.

Usage

To learn more about how to run the program with different options, run python -m twbodyproblem -h or python3 -m twbodyproblem -h respectively.

Run the program with python -m twobodyproblem or python3 -m twobodyproblem.

First, you will have to input options and values. The options define the particular behavior of the simulation, the values define the dimensions (i.e. mass, radius, distance, velocity) of the bodies.

The simulation will start automatically after the last input.

During the simulation, you are able to pause, un-pause and stop the simulation with the accordingly named buttons below the black rectangle. The restart button restarts the whole program, not just the simulation.

The sliders below the buttons can be used to magnify the bodies in the simulation. This magnification does not affect the physics, it is only a visual help.
