Pseudo-static behavior of rockfill dams with a dry-stone pitching: A mixed FEM-DEM approach
Oct 25, 2022
The webinar presents the validation of the mixed continuum-discrete FEM-DEM approach. It is done by modeling, using FLAC3D and PFC3D ITASCA software, pseudo-static experiments carried out on scaled-down rockfill dams with dry-stone pitching.
A numerical model of a full-scale dam is then built using this validated approach. The construction phases and reservoir filling processes are modeled. Then, the dam seismic resistance is evaluated by performing pseudo-static tests provided by tilting the dam until failure.

Meshing Solutions in 3DEC
Jun 22, 2021
The webinar presents new tools available in 3DEC 7.0 to simplify and speed-up model construction.
This includes: building block models directly from arbitrary geometry data (imported from CAD), creating a grid that conforms to a topographic surface, an advanced meshing generator which provides greater control on the size of meshes at specific points and surfaces and allows mesh gradation within blocks, the capability to generate Voronoi blocks and many more features. The webinar will provide examples of applications and guidance on what meshing solution to choose depending on your problem.

Evaluation of impacts of lahars on structures using DEM numerical modeling
Jan 19, 2021
Lahars represent natural phenomena that can generate severe damage in densely populated urban areas. The evaluation of pressures generated by these mass flows on constructions (buildings, infrastructure…) is crucial for civil protection and assessment of the structures’ vulnerability. The existing tools developed to model the spread of flows at large scale in densely populated urban areas remain inaccurate in the estimation of mechanical efforts.

The Art of Numerical Modelling in Geomechanics
Feb 27, 2020
Presented by Dr. Peter A. Cundall: Numerical modeling is widely used in Geomechanics for design and diagnostic purposes, but there is an art to using the software tools correctly. It's not just a case of plugging in the data, and hitting "run". We need to understand the underlying physics, and whether the model properly represents it.
