ITASCA_FLAC_2D_V5.0.355
(Fast Lagrangian Analysis of Continua) is a powerful two-dimensional continuum code for modeling soil, rock and structural behavior. Used interactively or in batch mode, FLAC is a general analysis and design tool for geotechnical, civil, and mining engineers that can be applied to a broad range of problems in engineering studies.
The explicit finite difference formulation of the code makes FLAC ideally suited for modeling geomechanical problems that consist of several stages, such as sequential excavation, backfilling and loading. The formulation can accommodate large displacements and strains and non-linear material behavior, even if yield or failure occurs over a large area or if total collapse occurs

ITASCA_FLAC_3D_V3.0.1
FLAC3D is a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions.
FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers. It is designed to accommodate any kind of geotechnical engineering project where continuum analysis is necessary.
FLAC3D utilizes an explicit finite difference formulation that can model complex behaviors not readily suited to FEM codes, such as: problems that consist of several stages, large displacements and strains, non-linear material behavior and unstable systems (even cases of yield/failure over large areas, or total collapse

Distinct Element Modeling for Micromechanical Analysis of geomaterials and particulate systems in two and three dimensions
PFC2D and PFC3D (Particle Flow Code in 2 Dimensions; Particle Flow Code in 3 Dimensions) are discontinuum codes used in analysis, testing, and research in any field where the interaction of many discrete objects exhibiting large-strain and/or fracturing is required.
Because PFC2D and PFC3D are not designed to examine a particular type of problem, their range extends to any analysis that examines the dynamic behavior of a particulate system.
PFC uses an explicit solution scheme that gives stable solutions to unstable processes. It can describe non-linear behavior and localization with accuracy that cannot be matched by typical finite element programs. This makes PFC2D and PFC3D the only commercially available codes of their kind.
The efficient contact detection scheme and the explicit solution method ensure that a wide variety of simulations — from rapid flow to brittle fracture of a stiff solid — are modeled accurately and rapidly. All the equations used in PFC are documented. The user has access (via the powerful built-in program-ming language, FISH) to almost all internal variables. The codes are not “black boxes,” but open software that can be used with confidence.

ITASCA_3DEC_V4.0
3DEC is a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. 3DEC simulates the response of discontinuous media (such as jointed rock) that is subject to either static or dynamic loading.
3DEC Facts
3DEC has been available for more than 18 years and is used by engineers, consultants, and researchers in more than 30 countries around the world.
3DEC is an accurate and efficient geotechnical analysis tool, using an explicit solution scheme that gives stable solutions to unstable processes. 3DEC can model mine-scale operations and large structural complexes.
Because Itasca is both an engineering consulting firm and a software developer, 3DEC is developed in a practical environment driven by considerations derived from real-world problems. We know what those problems are, because we tackle them every day
UDEC (Universal Distinct Element Code) is a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in two dimensions. UDEC simulates the response of discontinuous media (such as jointed rock) that is subject to either static or dynamic loading.
UDEC is a discontinuum code that simulates either the quasi-static or dynamic response to loading of rock media containing multiple, intersecting joint structures. Because it is not limited to a particular type of problem or initial condition, UDEC may be applied to any case where an understanding of the two-dimensional response of such structures is needed.
UDEC provides rigid or deformable blocks, multiple material models, full dynamic capability, and high resolution graphics to expedite the modeling process. Solution parameters may be specified by the user, maximizing the user's control over the duration, extent, and efficiency of the model run. Additional control and customization are available to the user through UDEC's powerful built-in programming language, FISH.
