The ITASCA Symposium will take place at the world famous CN Tower. The main theater and meeting rooms we will be using for the presentations, workshops, and coffee breaks will be at the base of the CN Tower.
At 114 stories above ground level, the Reception and Award Ceremony will be held on the Observation Level (cityside) prior to the Banquet Dinner within the 360 Restaurant. LEARN MORE about the CN Tower.
Four in-person workshops will be offered at the Symposium for the those interested in refreshing or expanding their abilities with ITASCA software. The workshops will be held, in parallel sessions, on Thursday, June 6, 2024. Each of these workshops has a participation fee of CND$180 (CND$90 for student registrants). For those interested in IMAT (ITASCA Mining Analysis Toolbox), a fifth workshop being held June 5-6, 2024 at the Toronto Marriott City Centre Hotel, the participation fee for this workshop is CND$200 + 13% GST. Note there is a separate registration link for the IMAT Workshop (see below).
June 6 - MORNING (8 am – 12 noon)
PYTHON AND ADVANCED FISH — Room A (TBD), Chris Thielsen and Jim Hazzard
Join us for an overview of Python and working with Python in ITASCA software for the first half of this workshop. Learn about the Python modules which are included with ITASCA software and how to add new modules. This workshop is suitable for those who have never used Python before or for advanced Python users interested in working with Python in ITASCA software.
For the second half of this workshop, advanced FISH capabilities will be reviewed; including working with lists, splitting, multithreading, and file read/write. The use of multithreaded FISH will greatly enhance the capability and performance of FISH scripting, especially for very large models and when using scripting during model cycling.
It is recommended that you bring your laptop, but not required. A two-week long trial version of the latest ITASCA software will be distributed as part of this workshop. All project and data files reviewed will be provided plus the slides (as PDFs).
LIQUEFACTION OF MINE TAILINGS — Room B (TBD), Zhāo Chéng
Join us for a review of numerical modeling static liquefaction of mine tailings using Itasca software FLAC2D or FLAC3D version 9. Static liquefaction has been in the spotlight as it has been associated with numerous recent failures of tailings storage facilities (e.g., the 2019 failure of Dam I at the Corrego de Feijao mine in Brumadinho, Brazil) and water reservoir dams (e.g., the 2020 failure of Edenville dam in Michigan).
This half-day workshop will discuss core concepts of static liquefaction based on the critical state soil mechanics framework and outline how to assess static liquefaction through numerical modeling. Goals for this workshop include:
A two-week long trial version of the latest ITASCA software will be distributed as part of this workshop and all slides will be made available as PDFs.
LUNCH (12 noon to 1 pm, on your own)
June 6 - AFTERNOON (1 pm – 5 pm)
MACHINE LEARNING FOR GEOENGINEERS — Room A (TBD), Chris Thielsen
Join us for a brief introduction to machine learning as it applies to geomechanics. The workshop starts with an introduction to machine learning and surrogate modeling. The workshop will discuss the advantages of each methodology and highlight the capability of numerical simulations to empower machine learning, finishing with a review of two real-world projects that involved the use of machine learning. The goal of this course is to demystify machine learning for those that still see it as a buzzword and demonstrate that machine learning should be part of the standard engineering problem-solving “toolbox”. A two-week long trial version of the latest ITASCA software will be distributed as part of this workshop and all slides will be made available as PDFs.
TUNNEL MODELING FOR CIVIL ENGINEERS — Room B (TBD), Marco Camusso and Jim Hazzard
Join us for an overview of modeling tunneling using ITASCA software. The workshop will describe recommended procedures for tunnel modeling including 2D versus 3D analysis, mesh generation tools, simulation of different support systems (including non-linear support), consideration of water, the latest constitutive models, and the post-processing of the model results. Instruction will be delivered mostly through the working of practical examples. Previous experience with ITASCA software is beneficial but not essential. A two-week long trial version of the latest ITASCA software will be distributed as part of this workshop and all slides will be made available as PDFs.
FULL TWO-DAY (June 5 - 6)
IMAT IMMERSIVE TRAINING — Raptor Room (Toronto Marriott City Centre Hotel), Gys Basson

Powerful Integration: Witness the synergy between the FLAC3D solver and advanced seismic data analysis.
User-Centric Design: Unlock the potential of advanced concepts with ease.
Unlock the full potential of IMAT during our exclusive hands-on training workshop running parallel to the conference. Here's a sneak peek into what awaits you on each day:
Day 1: June 5 - Introduction to IMAT: Combining Seismology and Numerical Modeling
The integration of Seismology and Numerical Modelling presents a synergistic approach for acquiring a comprehensive understanding of subsurface geological conditions. Presently, mining operations frequently necessitate the expertise of external consultants to navigate the interface between these two disciplines. During this session, our objective is to dispel this prevailing misconception by elucidating seismological principles in a straightforward manner.
Agenda Highlights:
Day 2: June 6 - Using IMAT to Build and Post-process Mine Scale Models
Hands-on Experience
Why Attend?
The Peter A. Cundall Award is presented to the best overall Extended Abstract at an Itasca Symposium. A certificate and award is presented to each author and they are invited to present one of the Symposium keynote addresses. Honorable mentions may also be recognized.
The winner is selected by a committee of Itascans, including Dr. Cundall, based on recommendations by the Symposium Technical Committee. Employees of Itasca International do not qualify.
Dr. Cundall was instrumental to the conceptualization and development of Itasca's FLAC, FLAC3D, UDEC, 3DEC and PFC software. Dr. Cundall performed his doctoral work at Imperial College, London, where, in 1971, he originated the Distinct Element Method for modeling jointed rock and granular material. In addition to being an independent consultant for several years, he worked for Dames and Moore for five years, was a faculty member at the University of Minnesota for seven years at which he is now Adjunct Professor. He was employed by Itasca for more than 20 years, and remains an Associate with Itasca. Dr. Cundall is a Fellow of the Royal Academy of Engineering and Member of the National Academy of Engineering.
