50.3.1 setValues(...)

This method modifies the Control object.

Required arguments

None.

Optional arguments

allowPropagation

A Boolean specifying whether to allow all control values to propagate from a previous step. Setting this argument to ON automatically sets resetDefaultValues to OFF. The default value is ON.

resetDefaultValues

A Boolean specifying whether to use all default control values. Setting this argument to ON automatically sets allowPropagation to OFF. The default value is OFF.

discontinuous

A Boolean specifying whether to set timeIncrementation values that will usually improve efficiency for analyses with severely discontinuous behavior. The default value is OFF.

constraints

The SymbolicConstant DEFAULT or a sequence of Floats specifying tolerances on constraint equations. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

lineSearch

The SymbolicConstant DEFAULT or a sequence of Floats specifying line search control parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

timeIncrementation

The SymbolicConstant DEFAULT or a sequence of Floats specifying time incrementation control parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

directCyclic

The SymbolicConstant DEFAULT or a sequence of Floats specifying direct cyclic control parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

concentrationField

The SymbolicConstant DEFAULT or a sequence of Floats specifying mass concentration field equilibrium equation parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

displacementField

The SymbolicConstant DEFAULT or a sequence of Floats specifying displacement field and warping degree of freedom field equilibrium equation parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

electricalPotentialField

The SymbolicConstant DEFAULT or a sequence of Floats specifying electrical potential field equilibrium equation parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

globalField

The SymbolicConstant DEFAULT or a sequence of Floats specifying parameters for all applicable field equilibrium equations. This argument overwrites all other field equilibrium equation control values. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

hydrostaticFluidPressureField

The SymbolicConstant DEFAULT or a sequence of Floats specifying hydrostatic fluid element volume constraint parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

poreFluidPressureField

The SymbolicConstant DEFAULT or a sequence of Floats specifying pore liquid volumetric continuity equilibrium equation parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

rotationField

The SymbolicConstant DEFAULT or a sequence of Floats specifying rotation field equilibrium equation parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

temperatureField

The SymbolicConstant DEFAULT or a sequence of Floats specifying temperature field equilibrium equation parameters. If a specified sequence contains a value of 0, that item in the sequence will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

vcctLinearScaling

The SymbolicConstant DEFAULT or a Float specifying linear scaling parameter for a VCCT debonding analysis. If a specified value is 0, it will be set to its system-defined value. The value can also be the SymbolicConstant DEFAULT. The default value is DEFAULT.

Return value

None

Exceptions
