Itasca Australia Pty Ltd.
Software
One particular aspect that makes Itasca unique among geotechnical and mining consulting firms is our development of advanced numerical simulation programs in hydrogeology and soil and rock mechanics. We develop and market the most widely used geomechanics simulation software in the world. The Itasca software codes include the two and three-dimensional continuum programs FLAC and FLAC3D, the two and three-dimensional discontinuum programs UDEC and 3DEC and the two and three-dimensional particle-flow simulation programs PFC2D and PFC3D. These programs are used by over 3000 mining and civil construction companies, consultants in rock and soil mechanics and university and government researchers worldwide. The Itasca codes are used for design of major mining and civil construction projects, design of nuclear waste repositories and oil-reservoir treatment programs, and have been used in a large portion of rock mechanics research projects worldwide. We often perform custom modification or development of these programs for specific project or client needs. Development of all software is governed by input from our consulting practice. Consequently, clients are assured that these numerical modelling codes are practical, efficient analysis tools with a proven record of solutions to real-world problems.
Itasca Australia serves as the software agent for Australia, New Zealand, Papua New Guinea, the Philippines, and Indonesia. Training courses on the use of all Itasca software are held on a regular basis. Specific training needs can also be supplied on an as-needed basis.
FLAC / FLAC3D
Two and three-dimensional explicit finite-difference codes developed as general analysis tools for geotechnical, civil and mining engineers. These codes are ideal for modelling geomechanical problems that consist of several stages, such as sequential excavation, backfilling and seismic loading. The codes simulate the behaviour of structures built of soil, rock or other materials that undergo inelastic deformation when their yield limits are reached.
PFC2D / PFC3D
Two and three-dimensional distinct element codes for modelling the static or dynamic response of discontinuous systems (such as a jointed rock mass). The codes address the engineering problems associated with a range of applications including mining, studies of underground isolation of radioactive materials, energy resource recovery, stability analysis of dams on jointed rock foundations, earthquake and seismology studies and underground structures in jointed rock.
UDEC / 3DEC
Two and three-dimensional distinct element programs for modelling the movement and interaction of assemblies of arbitrarily sized circular particles. The codes create an ideal environment for study of the behaviour of synthetic materials, modelling bulk flow and mixing materials and studies of micro and macro-cracking in solid bodies (including damage accumulation leading to fracture, dynamic breakage and seismic response).
