ElementJacobianDamper

Damper that limits the change in element Jacobians

This damper limits the change in the Jacobians of elements. The damper becomes active if the relative change in Jacobian of any element exceeds the user defined maximum.

Input 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

  • use_displaced_meshTrue

    Default:True

    C++ Type:bool

  • displacementsThe nonlinear displacement variables

    C++ Type:std::vector

    Description:The nonlinear displacement variables

  • max_increment0.1The maximum permissible relative increment in the Jacobian per Newton iteration

    Default:0.1

    C++ Type:double

    Description:The maximum permissible relative increment in the Jacobian per Newton iteration

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.
