EX3 (formerly Examine3D) is the newly revamped stress analysis software for quickly analyzing large, complex 3D underground models. EX3 uses the Boundary Element Method (BEM) – an efficient approach to elastic stress analysis that requires simpler discretization and meshing, since only surface meshes are implemented. The program comes with several exciting features including 3D modeling, geometry import and creation, geometry repairs tools, multiple staging for excavation and backfill, automatic surface meshing, and creation of field points for stress computation.
EX3 includes several innovative new tools including an improved surface meshing feature that lets users define mesh more precisely around areas of interest. It also includes a new “Grouping” function to help analyze mining sequences by allowing users to define the model with sequential stopes much easier.
With its combination of speed and simplicity, EX3 is the ideal tool for quickly performing complex stress analyses of underground mines.
