        - How is the model performance effected if the grain-size distribution is 
            wide or narrow?
       +- Create a landslide by turning the gravitational acceleration vector (set the 
       +    `y` component to a non-zero value, and setting the side boundaries to be 
       +    periodic with `Granular.setGridBoundaryConditions!(sim.ocean, "periodic", 
       +    "east west")`.
