On Unix-like systems simply run ./compile.sh. This will create a dist directory with the compiled binary.

cd dist./snowflake
The program saves the snowflake into four binary matrices: vapor mass (double), solid mass (double), liquid mass (double) and the snowflake's interior (boolean).
The Python file hex_grid.py contains a function to plot/export the different masses on the domain. A hexagonal grid is used to represent the underlying crystalline structure. A snapshot of the snowflake can also be exported.
