Overview

EX3 is advanced 3D boundary element software developed for geotechnical engineers analyzing underground excavations in rock. Utilizing the Boundary Element Method (BEM), EX3 provides high-efficiency simulation by discretizing only excavation boundaries, not the entire domain. This makes it ideal for modeling infinite or semi-infinite elastic domains found in tunnels, mining operations, and underground caverns. The software supports step-wise excavation modeling, material assignment, geometry import, and results visualization. EX3 also integrates with Rocscience’s RS3 software for deeper analysis, enhancing its utility across complex geomechanical workflows.

Features and Capabilities

• Boundary Element Method (BEM): Enables efficient stress analysis by only meshing excavation surfaces, reducing modeling complexity.
• **3D Geometry Import: **Supports .obj, .stl, .dxf, and .dwg file formats to load complex underground excavation models.
• **Multi-Stage Excavation Modeling: **Allows users to simulate excavation in multiple steps with support for backfilling and time-dependent changes.
• **Advanced Visualization Tools: **Displays stresses, displacements, and boundary conditions clearly across excavation surfaces and field points.
• **Integration with RS3: **Seamless model transfer to and from RS3 for enhanced numerical analysis, including geometry, materials, and in-situ stress.
• **Fast Multipole Method (FMM): **Accelerates boundary element calculations and minimizes memory usage for large-scale 3D simulations.
• **User-Friendly Interface: **Intuitive tools for geometry creation, snapping, material assignment, and boundary conditions configuration.
• **Application Scenarios: **Designed for tunnel design, mining operations, cavern analysis, and underground storage stability studies.
