Bonded Block Model undergoing Damage and Bulking during Simulated Relaxation

Continuum numerical modeling is inherently limited when the rock behavior involves mechanisms such as spalling and bulking. The Bonded Block Model (BBM) approach simulates the initiation of cracks that can coalesce and/or propagate leading to extension and shear fracturing, as well as the rock (e.g., intact, jointed, or veined) strength dependency on confinement.

How to Paint Model Data onto Geometry

3DEC, FLAC3D, and UDEC allow you to quickly analyze your model data by visualizing properties and results by “painting” zone field values onto some geometry (DXF, STL or GEOM format). Learn how this is done.

PFC 7 Balls in a Box

This tutorial will guide you through the main steps required to build a simple PFC model with 30 interacting balls in a box using the linear contact model.

Advanced three-dimensional geomechanical and hydrogeological modelling for a deep open pit

Graph-based flow modeling approach adapted to multiscale discrete-fracture-network models

In this study, we address the issue of using graphs to predict flow as a fast and relevant substitute to classical DFNs. We consider two types of graphs, whether the nodes represent the fractures or the intersections between fractures.

Numerical modeling of rock blasting: Validation tests for Blo-Up 2.5

As part of the Hybrid Stress Blast Model (HSBM) project, Itasca has developed software to model the rock blasting process.
