 ITASCA Geomechanical Modelling Codes

 ASC is the sales agent for Itasca's suite of geo-mechanical modelling codes in the UK and Ireland. 

Itasca is celebrating its 40th anniversary this year and to mark the occasion you can receive a 40% discount when you upgrade 3DEC, FLAC, FLAC3D, PFC, or UDEC version 4.0 (or earlier). This offer ends 31 December 2021.

Itasca's latest versions offer many new features and are optimized to run faster on today's computers. Upgrade to take full advantage of these advances to easily create, run, and analyse powerful numerical models.


Itasca suite of software solutions include the world’s most widely used set of commercial geomechanical-modeling software, along with software for hydrogeological analysis and geotechnical data visualisation. 

Itasca's suite of software for geomechanical and hydrological simulation includes:

PFC: Particle Flow Code, a general purpose distinct element modelling framework available in 2D and 3D.PFC models synthetic materials composed of an assembly of variably-sized rigid particles that interact at contacts to represent both granular and solid materials. 

FLAC: Fast Lagrangian Analysis of Continua, 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.

FLAC3DFast Lagrangian Analysis of Continua in 3D. A modelling software for geotechnical analyses of soil, rock, groundwater, constructs, and ground support. Such analyses include engineering design, factor of safety prediction, research and testing, and back-analysis of failure.

FLAC/Slope: A special, streamlined version of FLAC for evaluating the factor of safety (FoS) of soil and rock slopes in two dimensions with simple and fast model setup and analysis execution. 

3DECa 3D numerical modelling code for advanced geotechnical analysis of soil, rock, ground water, structural support, and masonry. 3DEC simulates the response of discontinuous media subject to either static or dynamic loading. The numerical formulation is based on the distinct element method (DEM) for discontinuum modelling. 

UDEC: Universal Distinct Element Code  is the 2D version of 3DEC that simulates the quasi-static or dynamic response to loading of media containing multiple intersecting joint structures.


KATSKinematic Analysis Tools for Slopes is a tool developed by Itasca that assesses instabilities caused by day-lighting wedges and planar failures formed when different structural sets interact with the orientation of a given slope.


XSitea powerful 3D hydraulic fracturing numerical simulation program based on the Synthetic Rock Mass (SRM) and Lattice methods. XSite is capable of modeling multiple wellbores with multiple stages and clusters, including open-hole completions and perforation tunnels.

MINEDWa 3D, finite-element, groundwater flow program that was developed specifically for mining applications. MINEDW is used worldwide to design dewatering or depressurization systems, predict local and regional environmental impacts of mine dewatering, assist in the design of water-supply systems, simulate the infilling of a “pit lake” after mining ceases, and estimate pore-pressure distributions within highwalls for geotechnical design purposes.
