 # Problem Definition 
-The problem is to simulate a rotating drum with the diameter **0.24 m**, the length **0.1 m** and **6** Baffles, rotating at **15 rpm**. This drum is filled with **20000** Particles.The timestep for integration is **0.00001 s**. There are 2 types of Particles in this drum each are beining inserted during simulation to fill the drum.
