Documentation and Theory Overview

EX3 (formerly Examine3D) is an engineering analysis program for underground excavations in rock. EX3 uses geometry modeling, surface mesh, and elastic stress analysis based on boundary element method with data visualization / interpretation.

With the rework of EX3, the program offers engineers user-friendly interface that is robust and efficient for analyzing complex underground mining excavations in rocks.

Getting Started

If you are a new user of EX3, you should begin by completing the EX3 – Tutorial 1 to help familiarize yourself with the software’s main functions.

How to Use this Guide

Documentation

The Documentation tab helps you to get familiar with program features and provides details on specific tools/functions of the software. This section includes topics like terminology, general features, input data, analysis methods, viewing and display options, and more.

Begin with the EX3 Project Settings page for an overview of the program’s analysis options.

Tutorials

The tutorials tab provides easy to follow, step-by-step instructions demonstrating how to use various features of the program and provide guidance for more specific analysis features of EX3. It is recommended that you go through as many of the tutorials as possible to get acquainted with the many different capabilities of the software.

Begin with the EX3 – Tutorial 1 for an introduction to the basic modelling and data interpretation features of EX3

Verification and Theory

The Theory and Verification tab contains a collection of Theory and Verification Manuals for the software. The Verification Examples represent an extensive set of models, from many different sources, which have been used to verify the accuracy of the solutions computed by the program. The Theory Manuals describes the equations used to calculate the stresses and the factor of safety as well as the theories behind the failure mechanisms of the Boundary Element Method (BEM).
