CannonBall

The CannonBall program is an example of using the SA::RK2Integrator to create a simple cannon ball simulation.

For each numerical integration time-step, the simulation program prints:

1. time (s)
2. 2D position vector (m)
3. 2D velocity vector (m/s)

to stdout, in Comma Separated Values (CSV) format.

Building & Running the Simulation Program

Generate the results as follows:

$ make
$ ./CannonBall > cannon.csv

Plotting the Results

The Python script, plot_trajectory.py is provided to plot the results in cannon.csv using (Python) matplotlib.

Plot the cannon ball trajectory as follows:

$ python plot_trajectory.py
