Numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support in two dimensions.
Itasca FLAC, Fast Lagrangian Analysis of Continua, is numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support in two dimensions. FLAC is used for analysis, testing, and design by geotechnical, civil, and mining engineers. It is designed to accommodate any kind of geotechnical engineering project that requires continuum analysis.
FLAC utilizes an explicit finite difference formulation that can model complex behaviors, such as problems that consist of several stages, large displacements and strains, non-linear material behavior, or unstable systems (even cases of yield/failure over large areas, or total collapse).
The program provides 17 built-in material models, groundwater flow, coupled mechanical-flow calculation, inclusion of structural elements, plotting statistical distribution of any property, optional automatic remeshing during solution, and a built-in scripting language (FISH) that can customize or automate virtually all aspects of program operation, including user-defined properties and other variables.
FLAC offers a fully integrated development environment that includes: project management facilities, built-in libraries of materials, pre-defined meshes, movies, extensive plotting capabilities, and run-time monitoring of results.
