Getting Started with FLAC2D/FLAC3D
Online
Sep 23, 2025 - Sep 24, 2025

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.

NEW TRAINING: Meshing in ITASCA Software
Online
Dec 2, 2025 - Dec 3, 2025

This introductory training course offers a comprehensive foundation in geotechnical modeling, enabling participants to identify various mesh types, effectively use the built-in tools in FLAC2D/3D and 3DEC, and gain practical experience with BlockRanger and Griddle for advanced mesh generation.


Software Tutorials

Generating Videos via Plots

This tutorial reviews how you can generate movies from FLAC3D plots. It is also applicable for 3DEC, PFC, and UDEC.

Creating Groups Interactively and Automatically using the Model Pane

In this tutorial, we review how to automatically skin models, identify and group zone faces, and interactively select and group zones and zone faces. This tutorial also illustrates using the Model Pane to interactively add a shell structural element along a tunnel.

An Introduction to Python Scripting: Part 2

Introduction to Python scripting by reviewing key concepts and through demonstrations. Part 2 focuses on classes and objects plus lists and dictionaries.

Technical Papers

Use of a Finite Element Code to Model Complex Mine Water Problems

Numerical models are now used routinely to predict ground-water inflows to both surface and underground mines and to help design dewatering systems.

Elastic Properties of Fractured Rock Masses With Frictional Properties and Power Law Fracture Size Distributions

We derive the relationships that link the general elastic properties of rock masses to the geometrical properties of fracture networks, with a special emphasis to the case of frictional crack surfaces.

We extend the well-known elastic solutions for free-slipping cracks to fractures whose plane resistance is defined by an elastic fracture (shear) stiffness ks and a stick-slip Coulomb threshold.

Influence of the particle shape on the impact force of lahar on an obstacle

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 physical vulnerability. The existing tools to model the spread of flows at large scale in densely populated urban areas remain inaccurate in the estimation of mechanical efforts. A discrete numerical model is developed for evaluating debris flow (DF) impact pressures at the local scale of one structure.
