Screenshots:

The screenshots show various stream flow visualizations done with this program.

The first screenshot shows an arrow plot with normalized vectors and a grid size of 32.
The background shows the strength of the stream flow in various colors.

This screenshot shows normal streamlines with random chosen start points. The streamlines were calculated by the Euler integration algorithm and with a Dt of 10.
The background also shows the strength of the stream flow.

---

This screenshot shows evenly-spaced streamlines with a d_sep of 20 and a d_test of 10. The streamlines were calculated using the Runge-Kutta integration algorithm and with a Dt of 5. The background shows the pressure distribution in various colors.

The last screenshot shows an arrow plot with normalized vectors and a grid size of 16. After the calculation of the arrow plot additional streamlines were inserted into the image using the Euler integration algorithm with a Dt of 5. The background once again shows the strength of the stream flow.
