Additional In Situ Analysis Method Available in SIGMA/W
SIGMA/W now has two In Situ analysis methods: (1) Gravity Activation, which was previously available; and (2) the K0 Procedure. The K0 Procedure requires that all materials applied to the domain have a valid K0 value. All material models now include a K0 Procedure tab that allows for specification or calculation of the at-rest earth pressure coefficient. The relationship used to calculate the at-rest earth pressure coefficient depends on whether the soil model has a friction angle or over-consolidation ratio defined, enabling the simulation of a range of stress histories.

Solute and gas transfer analysis
CTRAN/W is a powerful finite element software product for modeling solute and gas transfer in porous media. CTRAN/W can be used to model simple diffusion-dominated systems through to complex advection-dispersion systems with first-order reactions.
CTRAN/W can be used to model a vast array of geo-environmental problems involving the movement of dissolved species or gases that originate from either man-made or naturally occurring sources.

GeoStudio is an integrated software suite for modeling slope stability, ground deformation, and heat and mass transfer in soil and rock.
GEOSLOPE develops GeoStudio, the leading suite of geo-engineering software used in over 100 countries for the last 40 years. Join thousands of practising engineers, scientists, regulators, professors and students, and start using GeoStudio today.

Material Response Types Updated in SIGMA/W
Undrained and drained response types can be combined in a load-deformation analysis, making it possible, for example, to simulate a free draining material overlying a fully undrained material. In consolidation analyses, the response type is ignored as all materials are assumed to be consolidating. However, a material option was added to designate a material with 'no change in water pressures due to volumetric strain', allowing for the simulation of groundwater flow through all materials in the domain, while ensuring that some materials do not respond to loading/unloading. Finally, undrained behaviour is now simulated using effective stress stiffness properties instead of total stress stiffness properties.
