- The practical upscaling rules proposed and validated in this work allow for a dramatic reduction of computational costs. The efficiency and the ability to reproduce realistic behaviour of three different soils is presented. The computational speedup of the model led to pile penetration simulations in crushable sands for the first time (Ciantia et al., 2016; 10.1016/j.compgeo.2015.12.001) and directly contributed to the award of the inaugural ISSMGE Bright Spark Lecture in 2019 to Ciantia. The model is now listed in the user manual of the most used DEM commercial software (PFC by Itasca).
