MaxIncrement

!syntax description /Dampers/MaxIncrement

The MaxIncrement damper limits the change of a variable from one nonlinear iteration to the following iteration. A smaller value set as the max_increment will results in more nonlinear steps.

Example Input Syntax


[Dampers]
  [./max_inc_damp]
    type = MaxIncrement
    max_increment = 0.1
    variable = u
  [../]
[]

Input Parameters

variableThe name of the variable that this damper operates on
C++ Type:NonlinearVariableName
Description:The name of the variable that this damper operates on
max_incrementThe maximum newton increment for the variable.
C++ Type:double
Description:The maximum newton increment for the variable.

Required Parameters

min_damping0Minimum value of computed damping. Damping lower than this will result in an exception being thrown and cutting the time step
Default:0
C++ Type:double
Description:Minimum value of computed damping. Damping lower than this will result in an exception being thrown and cutting the time step
increment_typeabsoluteType of increment to compare against max_increment. 'absolue': use variable increment. 'fractional': use variable increment divided by the variable value.
Default:absolute
C++ Type:MooseEnum
Description:Type of increment to compare against max_increment. 'absolue': use variable increment. 'fractional': use variable increment divided by the variable value.

Optional Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Description:Set the enabled status of the MooseObject.
