Itasca 3DEC DP v5.20.277
3DEC is a 3D numerical modeling tool for advanced geotechnical analysis of soil, rock, sewage, structural support and masonry. The numerical formula of this software is based on the discrete element method (DEM) for discontinuum modeling. UDEC is its 2D version. Batch material is a set of discrete blocks. Unconformity is applied as a boundary condition between the blocks. Large displacements with discontinuity and rotation of blocks are allowed. The joint structure can be directly generated from geological mapping to the model.
