Itasca 3DEC is a 3D numerical modeller from Itasca for advanced geotechnical analysis of soil, rock, groundwater, structural support and masonry. The numerical formulation of this software is based on the discrete element method (DEM) for discontinuum modelling. UDEC is its 2D version. Discontinuous materials are represented as a set of discrete blocks. Discontinuities are treated as boundary conditions between blocks. Large displacements with discontinuities and rotations of blocks are allowed. The joint structure can be directly generated from geological mapping into the model. The software also includes the powerful Itasca built in FISH programming language. With FISH you can write scripts for users who wish to add functionality for custom analysis.
