DeformCalcType Deformation calculation type -
K0 procedure
This calculation type can be used to define the initial stresses for the model, taking into account the loading history of the soil.
Gravity loading
The phase will be calculated using a plastic calculation, in which initial stresses are generated based on the volumetric weight of the soil.
Flow only
The phase will be calculated using no effective stresses.
Field stress
This calculation type can be used to define a homogeneous initial stress state in the model, taking into account a rotation of principal stresses. This might be relevant for applications in deep soil or rock layers where the formation of these layers in the geological history has caused a rotation of principal stresses (shearing).
LoadingType Loading type -
Staged construction
Consolidation and simultaneous loading in the sense of changing the load combination, stress state, weight, strength or stiffness of the elements, activated by changing the load and geometry configuration or pore pressure distribution by means of staged construction.
Minimum excess pore pressure
Consolidation without additional loading, until all excess pore pressures have decreased below a certain minimum value, specified by the minimum pore pressure parameter.
Degree of consolidation
Consolidation without additional loading, until a desired degree of consolidation, specified by the degree of consolidation parameter, is reached.
Target SumMsf
Reduction of the soil and interface strength towards a target value of the total multiplier ΣMsf. The program first performs a full safety analysis until failure and then it recalculates the last step before the target value of ΣMsf in order to reach the target exactly.
Incremental Multipliers
Reduction of the soil interface strength parameters by using Incremental Multipliers option.
UseUpdatedMesh Use updated mesh -
True
Enables the use of an updated mesh.
False
Disables the use of an updated mesh.
MaxStepCount Max step count - The maximum number of steps for a phase
SubStepCount Sub step count - The number of sub-steps used for a phase
ArcLengthControl Arc length control - 1 if arc-length control is used, 0 if not and -1 if unavailable
MinIterations Min iterations - The desired minimum number of iterations. -1 if unavailable.
MaxIterations Max iterations - The desired maximum number of iterations. -1 if unavailable.
ToleratedError Tolerated error - The tolerated error. -1 if unavailable.
OverRelaxation Over relaxation - The over relaxation factor. -1 if unavailable.
