Geotechnical Software

Itasca develops geotechnical software for design of loads on, support of, and excavations in, soil, rock, and fractured rock for geomechanical, fluid-flow, dynamic, and thermal analyses. The following software are available commercially.

 

3DEC

3DEC is a three-dimensional numerical modeling code for advanced geotechnical analysis of soil, rock, ground water, structural support, and masonry. 3DEC simulates the response of discontinuous media (such as jointed rock or masonry bricks) that is subject to either static or dynamic loading. The numerical formulation is based on the distinct element method (DEM) for discontinuum modeling. UDEC is its two-dimensional version.

FLAC

FLAC, Fast Lagrangian Analysis of Continua, is numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support in two dimensions. FLAC is used for analysis, testing, and design by geotechnical, civil, and mining engineers. It is designed to accommodate any kind of geotechnical engineering project that requires continuum analysis.
 
FLAC utilizes an explicit finite difference formulation that can model complex behaviors, such as problems that consist of several stages, large displacements and strains, nonlinear material behavior, or unstable systems (even cases of yield/failure over large areas, or total collapse).

FLAC/Slope

FLAC/Slope uses the graphical interface and the automatic factor-of-safety calculation of FLAC as the core of an easy-to-use, function-specific code that models slope stability problems under a wide variety of slope conditions. These include: arbitrary slope geometries, multiple layers, pore pressure conditions, heterogeneous soil properties, surface loading, and structural reinforcement.

KATS

KATS (Kinematic Analysis Tools for Slopes) is a tool developed by Itasca S.A. that assesses instabilities caused by daylighting wedges and planar failures formed when different structural sets interact with the orientation of a given slope. The main application of the code is the so-called bench-berm scale analysis, which is understood as a first step in the mining slope design process for moderate and competent rock masses. It is also possible to perform a kinematic analysis in inter-ramp scale.

Unlike other tools currently available on the geotechnical analysis market, through a single automated process KATS performs a probabilistic or deterministic assessment of the behavior of a large number of slope configurations defined by many structural domains and many orientations and geometries of the slope. The results from the analysis can be provided using a variety of parameters, such as loss of crest, spill lengths, bench face angle distribution, etc. All these results allow a geometric definition of the interramp (IRA) angles that achieve the acceptability criteria defined by the operation from the point of view of stability and safety of personnel and equipment.

PFC

Particle Flow Code (PFC) Version 5 is an advanced, fast, and extremely versatile commercial, multi-physics simulation software for engineers and scientists using the Distinct Element Method (DEM). 

Drawing on Itasca's more than 25 years of pioneering DEM research, development, and experience, PFC sets the industry standard in performance, ease of use, accuracy, and versatility for manufacturing, mining, geotechnical, earth sciences, pharmaceuticals and packaging simulation.

PFC is available for two dimensional analysis (PFC2D) and as PFC Suite, which includes both PFC2D and, for three dimensional analysis, PFC3D.

UDEC

The Universal Distinct Element Code (UDEC) is a two-dimensional numerical program that simulates the quasi-static or dynamic response to loading of media containing multiple intersecting joint structures.

The discontinuous medium is represented as an assemblage of discrete blocks while the discontinuities are treated as boundary conditions between blocks. Large displacements along discontinuities and rotations of blocks can occur. UDEC utilizes an explicit solution scheme that can model complex, nonlinear behaviors. Models may contain a mix of rigid or deformable blocks.
