Your single point of reference for all your Geotechnical Inquiries


FLAC3D is a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions.

FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers. It is designed to accommodate any kind of geotechnical engineering project where continuum analysis is necessary.

FLAC3D utilizes an explicit finite difference formulation that can model 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).

Highlighted Features
•Large-strain simulation of continua, with interfaces or slip-planes to represent distinct interfaces along which slip and/or separation may occur, thereby simulating the presence of faults, joints, or frictional boundaries
•Explicit solution scheme that gives stable solutions to unstable physical processes
•Twelve built-in material models: the "null" model, three elasticity models, and eight plasticity models
•Available in 32-bit and 64-bit versions for Windows
