Abstract

With the recent technological advancements in terms of both hardware and software, DEM has increased in popularity among geotechnical engineers. This is due to its advantages when modelling large deformation problems over other numerical tools. Procedures have been created to enable fast generation of samples, but these tools have yet to reduce the run times of the civil engineering boundary value problems they are created for. In this paper a methodology has been described in which the particle refinement method and the periodic cell replication methods have been combined to create samples that are not only fast to generate but also reduce the run time of common geotechnical simulations, without reducing the resolution of the results obtained. An example sample is generated in this study and validated by modelling two geotechnical centrifuge pile installation tests.
