FLAC3D is a unique program for the continuous analysis of lagergia of various terrestrial phenomena. Although this program is a powerful product in the field of numerical computing and has many applications in mechanical science, but the main use of this program in the fields of civil engineering, mining and geomechanical issues in general. This program models and evaluates the nonlinear behavior of structures and formations constructed in soil, rock, and other similar materials. In fact, these environments are intertwined as interconnected elements. The geometry of each component is well defined and depends on the factors and metrics associated with it. The user is able to change the geometry used by changing these parameters. Although the changes may be linear, the result of changes in all elements may be nonlinear.
In this case, FLAC3D is able to model and evaluate these linear and nonlinear behaviors well. This program is Visual, but that doesn’t mean you don’t need coding, you need coding in some areas to model complex modes, as well as achieve great programming capabilities. In fact, the graphical interface of this program is provided to the user only for the simplicity of the modeling process. Professional users need coding to get the most out of the program. With this program, in underground excavations, the stability of the progress path and the strength and durability of supporting structures can be analyzed. Dynamic and static loading can be considered in dry and saturated environmental conditions. The relationship between soil, rock and other materials can be analyzed against related structures and many other geotechnical issues.
