Full-featured version of Irazu Geomechanical Simulation software included

In collaboration with Geomechanica

Introduction

In this course, we will provide an overview of numerical methods commonly used in rock engineering, including their limitations in dealing with problems involving large deformations and fracturing of discontinuous rock masses. Then, we will introduce the finite-discrete element method (FDEM), with a focus on theoretical aspects as well as computational and software implementation aspects. Finally, a large number of theoretical and practical case studies will be discussed with application to underground and surface mining, civil, and petroleum engineering.

Objectives

By attending this course, participants will learn about the basic concepts of numerical modeling for rock fracturing processes, available solutions, their pros and cons, as well as the FDEM method. Attendees will leave the course with a basic understanding of simulation approaches and in particular FDEM and how to apply FDEM to model complex engineering problems, such as underground excavations and slope stability analyses. Participants will learn how to build FDEM models in Geomechanica’s Irazu software, including the assignment of correct input parameters and postprocessing of the results.

Prerequisites: A basic understanding of rock mechanics and numerical modeling is required.


Course participants will receive a free, full-featured version of Geomechanica’s flagship Irazu simulation software for the duration of the course. IRAZU is a versatile 2D/3D finite-discrete element software package for the analysis of large deformations, fracturing, and stability in rock masses.The integration of various multi-physics solvers and advanced features into a single software package enables Irazu to be used for a wide range of geo-engineering applications, including but not limited to underground excavations, slope stability, tunnelling, dynamic analysis, mining, and reservoir geomechanics.
