Deformation feature on a phase, containing calculation parameters relevant to the deformation calculation.

Property	Long name	Unit	Description
Name	Name	-	Name of the deform feature.
Comments	Comments	-	Comments on the deform feature.
UserFeatures	UserFeatures	-	UserFeatures of the deform feature object.
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 Multiplies 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.
UseDefaultIterationParams	Use default iteration parameters	-	True Default parameters will be used for the iterative procedure. False Parameters used for the iterative procedure will be defined manually.
OverRelaxation	Over relaxation	-	Over relaxation factor that is used to reduce the number of iterations needed.
ArcLengthControl	Arc length control	-	On Phase will use arc length control. Off Phase will not use arc length control. Auto Use of arc length control will be decided by the kernel.

ResetDisplacementsToZero	Reset displacements to zero	-	True Displacements will be reset to zero in this phase. False Displacements will not be reset to zero in this phase.
ResetSmallStrain	Reset small strain	-	True Small strains will be reset to zero in this phase. False Small strains will not be reset to zero in this phase.
ResetTime	Reset time	-	True Time parameter will be reset to zero in this phase. False Time paramter will not be reset to zero in this phase.

FirstTimeStep	First time step	-	User-defined first time step, which overrides the critical step.
MinTimeStep	Minimal time step	-	Minimal time step value.
MaxTimeStep	Maximal time step	-	Maximal time step value.
MaxLoadFractionPerStep	Maximum load fraction per step	-	Amount of load fraction per step.
MaxIterations	Maximum iterations	-	Maximum allowable number of iterations within any individual calculation step.
MaxUnloadingSteps	Maximum unloading steps	-	Maximum allowable number of unloading steps until failure is assumed.
ToleratedError	Tolerated error	-	Maximum allowed error of the numerical calculation.
