In this Case we have two types of Particle with 4mm and 5mm diameters.
At the end of `caseSetup`, the interaction between the particles and the Shell of Rotating Drum is defined. You can see the Coefficients of the Interactions between the particles and shell of Rotating Drum in `interaction`.
At the end of `caseSetup`, the interaction between the particles and the Shell of Rotating Drum is defined. You can see the Coefficients of the Interactions between the particles and shell of Rotating Drum in `interaction`. Because we have 3 kind of interactions between these Particles and the Drum, we need to define a 3*3 Matrix.

## Settings
### Geometry
In the Settings folder the Specifications of our Rotating Drum and the information of rotating axis are brought. In this case we use two solid cylinders to keep our rotating drum isolated. This is to prevent particles, from being thrown out.
