This training is an introduction to continuous modeling with FLAC2D and FLAC3D. At the end of the course, participants will master the graphical interface, documentation and the main modeling steps. Concepts are illustrated using a tunnel excavation example, from building the model geometry to results analysis. This introductory course provides the foundation for more advanced use of the software, which can be covered in more specific training modules.

Ease Of Use
3DEC models use a combination of interactive tools and commands. 3DEC simplifies modeling with interactive features such as CAD file compatibility, built-in mesh generation, intuitive boundary skinning, and automatic stress initialization. For advanced meshing, use Griddle and Rhino 3D CAD to build and precisely mesh complex models as a 3DEC grid. Easily define groups in the model pane and assign constitutive models and material properties using the built-in database.
Speed
3DEC utilizes multi-threading and optimized solutions for fast, responsive, and accurate simulations. Multi-threaded FISH and Python libraries provide extremely efficient model scripting when user customization is chosen. Users may also run two instances of 3DEC on the same computer simultaneously, cutting down on overall time to solution for multiple models.
Powerful Capabilities
3DEC offers robust hybrid (DEM + continuum) simulation capabilities to model blocks of discontinuous material (jointed rock or masonry bricks). Blocks may be rigid or deformable (zoned) and may slide, rotate, move apart, or come together. Uniquely model groundwater flow within joints and though the ground between them. Coupled mechanical, hydro, and thermal solutions.
Run dynamic analysis to simulate earthquakes and structural elements for ground support are available. Statistical joint set and DFN generation tools are built-in. Advanced plotting tools, FISH scripting and Python integration provide unparalleled model control and customization, while statistical tools and data import options expand modeling possibilities.
Commands
In conjunction with interactive tools, 3DEC uses commands to provide a compact representation of the model (as a data file) for repeatability, to ensure path dependency (excavation sequence and any other sequence of events, such as boundary conditions or material properties), and for flexibility.
Intuitively structured commands, built-in contextual help, and command auto-completion help users learn and work with commands. Most user interface interactions are automatically translated into commands, so you can see how they are composed and reuse them. The built-in text editor makes creating and running models with commands efficient.

MORE TO LOVE
Dynamics
3DEC offers three-dimensional, fully dynamic, analysis that extends simulation capabilities to a wide range of dynamic problems in earthquake engineering, seismology, hydraulic fracturing, gravity flow, blasting, and deep underground rockbursts.
You can specify acceleration, velocity, or stress waves as an exterior or interior boundary condition and include wave absorbing and free-field boundary conditions. Simulate and record synthetic microseismicity for model calibration and validation. Dynamics supports ground-structure interaction, can be coupled to thermal analysis, and includes a Dynamics Wizard to pre-process ground motions. Couple Dynamics to groundwater flow for analyses involving time-dependent pore pressure change associated with liquefaction.

Thermal
3DEC’s thermal analysis allows the simulation of transient heat conduction for modeling geothermal, ground freezing, and nuclear waste applications. The thermal logic includes a highly accurate numerical formulation for short time scales that includes thermal-mechanical fluid coupling; and a very fast analytical formulation for long time scales.
IMASS
3DEC’s IMASS features a two-mode softening of yield surfaces, offering a refined approach to modeling. Notably, IMASS introduces a set of novel material properties and integrates cutting-edge techniques for apex correction, automatic testing, and property updates and management.
