Utilisation of DEM simulation of bulk materials in practice
Many transport and process systems in practice does not work entirely by the operator concepts. The operator then often perform a variety of structural or technological adjustments of the equipment according to the intuition or from experience with similar equipment already functioning or on the basis of methods "trial - error". Any such even unsuccessful attempt ending in failure is beneficial, however, materially, financially and time-consuming. The article presents the option to verify the functionality of proposed modifications in the transport and process equipment not on the physical model, but using a simulation of movement of bulk materials based on numerical methods. This method is known as Discrete Element Method, abbreviated as DEM (Metoda diskrétních prvků in Czech).
