# 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.
