# Problem Definition # Problem Definition
The problem is to simulate a double pedestal tote blender with the diameter **0.03 m** and **0.1 m** respectively, the length **0.3 m**, rotating at **28 rpm**. This blender is filled with **20000** Particles. The timestep for integration is **0.00001 s**. There is one type of Particle in this blender that are being inserted during simulation to fill the drum.
