ComponentsConvergence

This IterationCountConvergence can be used with the Components system to check the convergence of all Components that return a Convergence object with getNonlinearConvergence(). The inner convergence check returns its convergence status as follows:

CONVERGED: All Convergence objects created by Components are CONVERGED
DIVERGED: Any Convergence object created by a Component is DIVERGED
ITERATING: Not CONVERGED nor DIVERGED

Input Parameters

converge_at_max_iterationsFalseConverge at 'max_iterations' instead of diverging
Default:False
C++ Type:bool
Controllable:No
Description:Converge at 'max_iterations' instead of diverging
max_iterations50Maximum number of iterations
Default:50
C++ Type:unsigned int
Controllable:No
Description:Maximum number of iterations
min_iterations0Minimum number of iterations
Default:0
C++ Type:unsigned int
Controllable:No
Description:Minimum number of iterations
verboseFalseEnable printing of additional information, including convergence and divergence reasons.
Default:False
C++ Type:bool
Controllable:No
Description:Enable printing of additional information, including convergence and divergence reasons.

Optional Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:No
Description:Set the enabled status of the MooseObject.
implicitTrueDetermines whether this object is calculated using an implicit or explicit form
Default:True
C++ Type:bool
Controllable:No
Description:Determines whether this object is calculated using an implicit or explicit form
