Interactive solid-based mapped hexahedral meshing.The KUBRIX® family of software covers nearly every grid generation need of today's advanced engineering packages: Solid mechanics and micro-damage of intact materials and.Integrity of radioactive waste storage facilities.Stability analysis of jointed rock slopes.UDEC is capable of simulating and is used for a wide range of engineering and scientific analyzes including: Joint models and properties can be assigned separately to individual, or sets of, discontinuities.īecause it is not limited to a particular type of problem or initial condition, UDEC may be applied to a wide variety of physical behaviors or any case where an understanding of the two-dimensional response of such structures is needed. The relative motion of the discontinuities is also governed by linear or nonlinear force-displacement relations for movement in both the normal and shear directions. Deformable blocks are defined by a continuum mesh of finite-difference zones, with each zone behaving according to a prescribed linear or nonlinear stress-strain law. Models may contain a mix of rigid or deformable blocks. UDEC utilizes an explicit solution scheme that can model complex, non-linear behaviors. Large displacements along discontinuities and rotations of blocks can occur. The discontinuous medium is represented as an assemblage of discrete blocks while the discontinuities are treated as boundary conditions between blocks.

Two case studies are presented showing the capabilities of the hybrid approach.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).ĭrawing on Itasca's pioneering DEM research, development and experience that spans over a quarter of a century, PFC sets the industry standard in performance, ease of use, accuracy and versatility for manufacturing, mining, geotechnical, earth sciences, pharmaceuticals and packaging simulation. Two of the main advantages of the hybrid approach include the capability of studying the potential impacts of isolated draw on cave growth and point loading on the extraction level, as well as the effect of including, explicitly, the airgap and mechanisms of fines migration and rilling on cave growth and subsidence.

The procedure is repeated until the draw schedule used as an input in REBOP is finished. FLAC3D informs REBOP which zones (initially inactive) could now be mobilised. FLAC3D solves stresses associated with the presence of these zones and estimates the yielded zone surrounding the cave. After one cycle of extraction, REBOP informs the location of the movement zones and the presence of air, if it exists, to the continuum FLAC3D model. The approach simulates the caving process by explicitly modelling each isolated movement zone derived from REBOP into FLAC3D to determine the yielded zone and cave back associated with mass drawn. The results of the model can be used to derive estimates of: (i) caveability and caving rate, (ii) abutment stresses and cave loads, (iii) recovery and dilution entry, (iv) fragmentation, and (v) breakthrough timing and subsidence. The hybrid REBOP–FLAC3D approach allows prediction of the limits of the geomechanical zones defining the cave as a function of production.
