FLAC, Fast Lagrangian Analysis of Continua, is 2D numerical modeling software for advanced geotechnical analysis of soil, rock, groundwater, and ground support. It utilizes an explicit finite difference formulation.
The SoilTest option is a quick and convenient procedure to simulate basic soil lab tests. It also offers the possibility to optimise model parameters. It works for any model, both standard soil models as well as user-defined models.
A dedicated special purpose incremental driver which is able to calculate the results of homogeneous experiments. Both displacement controlled and force controlled experiments can be performed.
ExCalibre is online tool for automatic calibration of soil constitutive models, adopting a unique model-specific calibration algorithm respecting physical meaning of material parameters. Experimental data are read from a simple Excel spreadhseet template.
Incremental Driver is a single element code developed by Andrzej Niemunis (2007, 2014) for running element tests using constitutive models implemented in umat format.
Triax is an inhouse element test constitutive model driver developed since 2001 at Charles University and elsewhere by David Mašín and coworkers. It covers wide range of constitutive models and testing conditions.
This program, based on the finite element method, can model and analyze a wide range of geotechnical problems, including terrain settlement, sheet pile/diaphragm walls, slope stability, excavation analysis.
SIGMA/W is a powerful finite element software product for modeling stress and deformation in earth and structural materials. SIGMA/W analyses may range from simple linear elastic simulations to soil-structure interaction problems with nonlinear material models.
