-
Automatic evaluation of initial stress conditions including steady state flow: combination of gravity and initial-stresses allows an automatic reproduction of the most complex initial state conditions, including existing constructions.
-
Stability analysis: through C-phi reduction and stress level algorithms lead to a reliable assessment of safety factors and failure surfaces for the most general problem geometries. Simpler and more general than usual sliding surface approaches. Possibility to analyze safety with respect to local material properties or features like contact surfaces.
-
Ultimate load analysis and deformation analysis.
-
Prestress conditions (anchors).
-
Simulation of Excavation, construction stages, simulation of fill for cut and cover construction: can be combined with any sequence of drivers, allowing removal or addition of construction parts, loads, boundary conditions etc., unloading control capability in order to simulate 3-dimensional effects in 2D. Continuous safety assessment.
-
Consolidation, volumetric and deviatoric creep and swelling (time dependent processes).
-
Flow, steady or transient, fully or partially saturated, with time dependent boundary conditions; fullly arbitrary flow conditions with free surface, seepage surfaces, as well as rain inflow, impermeable zones, coupled or uncoupled with solid deformation can easily be accounted for.
-
Thermal/or moisture migration analysis: Transient thermal/or moisture migration analysis can be performed as a preprocessing in order to define temperature time-histories to be accounted for later in the mechanical analysis.
-
Dynamic time integration and Pushover analysis for structures.
-
Skyline or new sparse solvers tested upto 100’000 dofs.
-
Stabilized finite element formulation for 2-phase media without time-step restrictions.
