SVOffice 2009 is a robust geotechnical / hydrological simulation code for subsurface processes. It models 1-D, 2-D, 3-D, time-dependent, nonisothermal, saturated and unsaturated flow of pore-water or air through soils. It models the deformations incited by foundational loadings and heave of unsaturated soils. The core of the package is a limit equilibrium slope stability analysis package. The package allows for easy coupling of effects between packages. SVOffice 2009 has been used to simulate groundwater and model slope stability by premier geotechnical consulting firms. The software is continuously maintained and new features implemented regularly by a dedicated team of engineers. The SVOffice 2009 platform includes the following six modules (which can be purchased separately or in any combination) to give you additional processing capabilities: SVSlope®, SVFlux™, SVHeat™, Chemflux™, SVSolid™, SVAirflow™.
