# Simulating a small rotating drum {#rotatingDrumSmall} # Problem definition (v-1.0)
## Problem definition (v-1.0)
The problem is to simulate a rotating drum with the diameter 0.24 m and the length 0.1 m rotating at 11.6 rpm. It is filled with 30,000 4-mm spherical particles. The timestep for integration is 0.00001 s. The problem is to simulate a rotating drum with the diameter 0.24 m and the length 0.1 m rotating at 11.6 rpm.

After finishing the simulation, you can render the results in Paraview. To convert the results to VTK format, just enter the following command in the terminal. This will converts all the results (particles and geometry) to VTK format and store them in folder `VTK/`. After finishing the simulation, you can render the results in Paraview.
