Getting Started with 3DEC
Online
Oct 22, 2024 - Oct 23, 2024

Objectives of the training:

  • Understand the 3DEC numerical approach and the types of problems it can solve
  • Know how to manipulate the 3DEC user interface to access and interpret results
  • Follow the recommended solution procedure to simulate a simple case

Python in Itasca Software
Online
Nov 5, 2024 - Nov 6, 2024

This course provides an overview of the Python programming language in Itasca software.

The course covers major applications of Python to extend modeling capabilities with the Itasca codes through many applied examples.


Getting Started with FLAC2D/FLAC3D
Online
Nov 19, 2024 - Nov 20, 2024

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.


Software Tutorials

FLAC3D 7 0 Octree Mesh Tutorial

In this example, a pile of earth is modeled overlying undulating ground. This tutorial demonstrates how a FLAC3D model mesh can be easily created using DXF geometries and the ZONE DENSIFY command. How to differentiate parts of the model into separate GROUPs using DXF geometries and the GEOMETRY-SPACE range logic is also demonstrated.

Proppant in Fluid Filled Joints

The transport and placement of proppant within fractures is modeled in 3DEC by representing the proppant and fracturing fluid as a mixture.

FLAC3D 7.0 Geometry Mesh Tutorial

This tutorial demonstrates how to generate a 3D volume mesh from surface geometry imported from DXF or STL files. Both hexahedral-dominant and tetrahedral meshes can be generated automatically using the "zone generate from-geometry ..." command in FLAC3D 7. The results of various keywords are shown.

Technical Papers

Input to Orepass Design — A Numerical Modeling Study

Orepass design guidelines required for potentially continued mining at depth. Rock strength and stress state were validated through comparison with observed fallouts in orepasses and shafts and the optimal orientation and location of orepasses for future mining were determined.

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.

Tunneldrivning i heterogena förhållanden

InledningProblem: Brist på erfarenhet av tunneldrivning i heterogena förhållanden med konventionell uttagsteknik (borrning och sprängning).

Mål: Fördjupa kunskapen och förståelse av brott och deformationsmönster vid dessa förhållanden.
