Ship Loader Simulation - Modified Geometry

The video shows the simulation a shiploader using the discrete element method (DEM). This simulation was perfomed to define the best possible configuration for the geometry of the shiploader to avoid material escaping. In the video it is possible to see that the resulting geometry has a good trajectory.
