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.
UDEC / 3DEC
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.
PFC2D / PFC3D
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).
