UDEC (Universal Distinct Element Code) is well suited for problems involving jointed rock systems or assemblages of discrete blocks subjected to quasi-static or dynamic conditions. UDEC addresses the engineering problems associated with mining, studies of deep underground isolation of radioactive materials, energy resource recovery, stability analysis of dams on jointed rock foundations, earthquake and seismology studies and subterranean structures.Product:ITASCA UDEC 4.00.153 Lanaguage:english Platform:Winxp/Win7 Size:6MB

PFC2D and PFC3D (Particle Flow Code in 2 Dimensions; Particle Flow Code in 3 Dimensions) are programs for modeling the movement and interaction of assemblies of arbitrarily-sized circular (2D) or spherical (3D) particles. The particles are rigid but deform locally at contact points using a soft contact approach, in which finite normal and shear stiffnesses are taken to represent measurable contact stiffnesses.The particles may represent individual grains in a granular material or they may be bonded together to represent a solid material, in which case, fracturing occurs via progressive bond breakage. Solution by the distinct-element method allows dynamic stress waves to propagate through the particle assembly, which may exhibit slip or separation, with unlimited displacement, under the action of applied...

FLAC/Slope uses the graphical interface and the automatic factor-of-safety calculation of FLAC as the core of a new, user-friendly code that models slope stability problems under a wide variety of slope conditions. These include: arbitrary slope geometries, multiple layers, pore pressure conditions, heterogeneous soil properties, surface loading, and structural reinforcement.FLAC/Slope uses the same calculation method as FLAC with a simplified modeling environment that provides tools and facilities exclusive to slope stability analyses. The result is a code that offers rapid model development, proven analytical capabilities, and fast solution reporting. Users of FLAC will find the FLAC/Slope modeling environment familiar. However, experience with FLAC is not necessary to learn and operate FLAC/Slope.FLAC/Slope is now available at or below the cost of...

FLEXIBLEFLAC3D is a continuum code that is used in analysis, testing, and design by geotechnical, civil, and mining engineers. FLAC3D has a large range of application because its analytical potential is not limited to a particular problem definition or type of analysis. FLAC3D is designed to accommodate any kind of geo-technical engineering project where continuum analysis is necessary.POWERFULFLAC3D is an accurate and efficient geotechnical analysis tool that utilizes an explicit finite difference formulation. FLAC3D can model a number of 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).FASTFLAC3D operates under all Windows platforms,...

3DEC (3-Dimensional Distinct Element Code) is the three-dimensional extension of Itasca‘s two-dimensional code UDEC. It is specifically designed for simulating either the quasi-static or dynamic response to loading of rock media containing multiple, intersecting joint structures. Main Features Simulation of large displacements (slip and opening) along distinct surfaces in a discontinuous medium Discontinuous medium treated as an assemblage of discrete polyhedra Discontinuities treated as boundary conditions between blocks Relative motion along discontinuities governed by linear and non-linear force-displacement relations for movement in both the normal and shear directions Explicit solution scheme, giving a stable solution to unstable physical processes Rigid or deformable blocks Library of material models for deformable blocks and for discontinuities Null blocks for excavation and nonlinear material...

After the input of all relevant parameters the test results can immediately be presented graphically on the screen. You can choose between different presentation forms and graphics:Tau-sigma diagram Stress paths Load-compression lines Pore water pressure-compression lines Stress ratio-compression lines Sigma 3-compression lines Volume-compression lines Protocol A MiniCAD system is available for additional labelling of graphics.Product:GGU Triaxial 3.13 Lanaguage:english Platform:Winxp/Win7 Size:1MB

[img]http://www.ggu-software.com/software/ggu-computation/transient/grundwassermodell_1.gif[/img]For a transient calculation of groundwater flow, a stable initial condition is required. This initial condition is found by the program GGU-TRANSIENT from a file (e.g. PLGW.DA1) which is created from a previous analysis undertaken with the program GGU-SS FLOW 2D. This data must be loaded as the first action after starting the program. In addition to the analysis results, the data file also contains the relevant soil and input parameters for the analysis.These fundamental parameters (e.g. k, neff etc.) cannot be modified in the GGU-TRANSIENT program. If they are altered, then the soil parameters will no longer match the potentials and flows, and the transient calculations will be meaningless. Of course, for all groundwater flow problems (planar vertical, planar...
