Simple solution implementation of the N Body Problem of Physics

N Body Problem

A quick implementation of the N Body Problem of Celestial Mechanics

Features

• Create Bodies with 3 initial parameters:

  param	dtype	description
  mass	float	mass of the body
  pos	np.array	position vector <i, j, k>
  vel	np.array	scape velocity vector <i, j, k>

• Create an NBPSolver with two parameters:

  param	dtype	description
  bodies	list	list of bodies
  ts	float	time step

• Utilize the NBPSolver method solve_timestep() to update each body's position after the specified time step has passed.

• Call the method plot_animation(time_lim, frame_size, output), where the parameters are:

  param	dtype	description
  time_lim	int	limit number of seconds
  frame_size	int	amount of iterations before recording a frame
  output	string	output file name (include file extension, e.g. output.gif)

• This package offers flexibility in terms of handling the output, as well as dinamically adding or removing bodies during run time.

TODO:

• Add different integration methods
• Add efficiency monitoring (*hint: create a context manager to monitor execution times)
