spiral_data, a C++ code which computes a velocity vector field that satisfies the continuity equation, writing the data to a file that can be plotted by gnuplot().

Source Code:

• spiral_data_test.cpp, calls all the tests.
• spiral_data_test.sh, runs all the tests.
• spiral_data_test.txt, the output file.

Sample data was generated with N = 20 and C = 0.45 and plotted with GNUPLOT:

• spiral_data.txt, the X, Y, U, V values.
• spiral_commands.txt, commands to GNUPLOT.
• spiral.png, the resulting plot.
