3D Stress Analysis for Underground Excavations

Boundary Element Method & Stress Analysis

Perform faster analysis of underground excavations using Boundary Element Method, which only requires meshing of the surface, resulting in simpler and more efficient discretization. Perfect for modelling infinite and semi-infinite elastic domains.

Full Scale Mine Analysis

Define and model large-scale mines with ease using advanced features in EX3. Import geometry, design excavations and backfill in different stages and visualize your results on the surface of the mine and pre-defined field points.

3D Geometry

Import a variety of 3D geometries including *.obj, *.stl, *.dxf, *.dwg, file types then analyze your models to find discrepancies and repair the geometry in minutes.

EX3 across Applications

Model any type of excavation and incorporate staged excavations with ease.

Efficient modelling of underground mines. Use pre-defined and user-defined results to investigate all aspects of your design.

Model underground tunnels to find stress intensity at the intersection of multi-crossing tunnels and more.

Explore the latest features in EX3

Better visualize stress and displacement distribution by defining the counter plane in a desired orientation in the field point box.

Pick any surface in your model and visualize the results of that specific area.

Use the property table to get a summary of all material and joint properties in the model and display them in their report.
