This training is an introduction to continuous modeling with FLAC2D and FLAC3D. At the end of the course, participants will master the graphical interface, documentation and the main modeling steps. Concepts are illustrated using a tunnel excavation example, from building the model geometry to results analysis. This introductory course provides the foundation for more advanced use of the software, which can be covered in more specific training modules.
A new plasticity bond damage model for highly porous, soft rocks is proposed and implemented as a contact model in the discrete element method DEM. The Particle upscaling law for strength, softening, and far-field interaction parameters are presented and validated in Zheng & Ciantia (2025) enabling computational efficiency. Also, a strength correction equation is developed in Zheng & Ciantia (2025) to consider sample size effect of rocks. Finally, for boundary value problems like pile installation, the computational improvement of the model led pile penetration simulations in porous, soft rocks for the first time conducted in Zheng & Ciantia (2025).
