This hands-on short course covers:
The finite-discrete element method (FDEM) is a numerical approach that combines continuum mechanics principles with discrete element algorithms to simulate multiple interacting deformable
and fracturing bodies.
With its ability to qualitatively and quantitatively reproduce failure processes in brittle materials, FDEM is gaining increasing acceptance in civil, mining, and petroleum engigneering applications, where fracture and fragmentation processes are key to fully understanding the rock mass behaviour.
Geomechanica’s Irazu software is a GPU-accelerated, thermo-hydromechanically coupled, FDEM-based modelling package capable of simulating the interaction between new fractures and pre-existing rock mass discontinuities in 2 and 3 dimensions.
This one-day course will combine theoretical lectures on the fundamental principles of FDEM with practical modeling sessions where participants will be guided through several simulation cases.
The course will start with a general introduction to the FDEM modelling philosophy and
its application to engineering geology, rock mechanics, and geophysics problems. After a quick review of the basic algorithms, such as finite element deformation, contact detection, and contact interaction, the fracture model will be discussed in more depth. More advanced features of Irazu, including: in-situ stress initialization, rock excavation, and Discrete Fracture Networks (DFNs), thermo-hydro-mechanical coupling, and rock support will also be introduced.
In the second part of the course, participants will gain valuable hands-on experience through a series of practical modelling exercises using Geomechanica’s Irazu software to model practical rock fracturing problems.
By attending this short course, participants will learn the basic concepts and algorithms embedded into FDEM and how to work with it.
Attendees will leave the course with a basic understanding on fracture development around an underground excavation of the FDEM simulation approach, its strengths, limitations, and how it can be applied to model complex engineering problems, such as underground excavations in discontinuous rock masses and hydraulic fracturing in unconventional plays.
Participants will learn how to build FDEM models in Geomechanica’s Irazu software, including the assignment of correct input parameters, and post processing of the results.
This one-day course is specifically designed for geotechnical, geological, mining and petroleum engineers, as well as undergraduate and post-graduate students and researchers.
In particular, anyone who wishes to use or is considering using FDEM to tackle challenging rock mechanics problems would benefit from this course.
The short course organizer will provide each participant with: (i) electronic copies of the course slides, (ii) electronic copies of the Irazu software manual and tutorials, and (iii) a free, full-featured demo version of the Irazu software.
