Tool to create videos of particles or waves in different 2D domains.

Created by Nils Berglund and optimized by Marco Mancini

C code for videos on YouTube Channel https://www.youtube.com/c/NilsBerglund

We plan to add a list of parameter values used in specific simulations later on.

There are two groups of 4 files:

Simulations of classical particles in billiards.

1. global_particles.c
2. sub_part_billiard.c
3. particle_billiard.c
4. drop_billiard.c

• Create subfolders 'tif_part', 'tif_drop'
• Customize constants at beginning of .c file
• Compile with

gcc -o particle_billiard particle_billiard.c-O3 -L/usr/X11R6/lib -ltiff -lm -lGL -lGLU -lX11 -lXmu -lglut

gcc -o drop_billiard drop_billiard.c-O3 -L/usr/X11R6/lib -ltiff -lm -lGL -lGLU -lX11 -lXmu -lglut

• Generate movie with

ffmpeg -i part.%05d.tif -vcodec libx264 part.mp4

Simulations of wave equation, heat equation and Schrodinger equation.

1. global_pdes.c
2. sub_wave.c
3. wave_billiard.c
4. heat.c
5. schrodinger.c

• Create subfolders 'tif_wave', 'tif_heat', 'tif_schrod'
• Customize constants at beginning of .c file
• Compile with

gcc -o wave_billiard wave_billiard.c -L/usr/X11R6/lib -ltiff -lm -lGL -lGLU -lX11 -lXmu -lglut -O3 -fopenmp

gcc -o heat heat.c -L/usr/X11R6/lib -ltiff -lm -lGL -lGLU -lX11 -lXmu -lglut -O3 -fopenmp

gcc -o schrodinger schrodinger.c -L/usr/X11R6/lib -ltiff -lm -lGL -lGLU -lX11 -lXmu -lglut -O3 -fopenmp

• Generate movie with

ffmpeg -i wave.%05d.tif -vcodec libx264 wave.mp4
