Abstract

Granular materials are a collection of distinct macroscopic particles. Consequently soils, which are used for agricultural purposes are a part of them. In comparison with other simulation models, creating a numerical simulation with the discrete element method (DEM) for different soils prove to be difficult. The reason for this is that there are an enormous number of particles. Therefore it is not possible to reproduce every one of them. On this account, parcels are used in the numerical simulation. These are larger and also have different physical properties. However, also for the modelling of parcels characteristic variables are necessary. This variable should be determined by using the capillary effect.
