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.
As well as flow through joints, 3DEC 5.2 is capable of simulating fluid flow through the blocks or the matrix (i.e., between the joints). It is assumed that the blocks represent a saturated, permeable solid, such as soil or fractured rock mass.
The flow in the matrix is coupled to the flow in the joints such that fluid in the joints can flow into the surrounding matrix (i.e., leak-off). As with the joint flow, the matrix flow modeling may be done independently of the usual 3DEC mechanical calculations or, in order to capture the effects of fluid/solid interaction, it may be done in conjunction (i.e., coupled) with the mechanical modeling.
