1D finite difference wave propagation
To compile the program run "make" in the terminal. It uses GNU g++ compiler. "./wave" will run the program. Results are saved to the results directory.
The modeling parameters (time, dx_ , stability, frequency_, s_time_delay_ , x_source, print_interval ) are specified in "input.txt" in this order.
velocity profile, "vel_profile.txt", contains three arguments in the following order: distance[m] density[kg/m^3] velocity [m/s].
Easy plotting with gnuplot. Type the following commends in the terminal:
-cd results/
-gnuplot
-do for [i=1:set_number] {plot "wave_signal".i.".txt" with lines ; pause 0.1; set xrange[0:x_max];set yrange[-1:1]};
