SingleParameterInverseSolve System
The SingleParameterInverseSolve block generates a complete fixed-point (Picard) inverse-solve workflow for a single time-dependent scalar parameter from one block.
See SingleParameterInverseSolveAction for the workflow, the complete list of generated objects, and the one required [Executioner] line (multiapp_fixed_point_convergence = single_parameter_inverse_solve_convergence).
Input Parameters
- absolute_tolerance1e-08Absolute tolerance on |output - target|.
Default:1e-08
C++ Type:Real
Unit:(no unit assumed)
Range:absolute_tolerance>0
Controllable:No
Description:Absolute tolerance on |output - target|.
- accept_on_max_iterationsFalseIf true, accept the current estimate when the fixed-point loop reaches max_iterations instead of diverging, cutting the time step, and erroring.
Default:False
C++ Type:bool
Controllable:No
Description:If true, accept the current estimate when the fixed-point loop reaches max_iterations instead of diverging, cutting the time step, and erroring.
- active__all__ If specified only the blocks named will be visited and made active
Default:__all__
C++ Type:std::vector<std::string>
Controllable:No
Description:If specified only the blocks named will be visited and made active
- inactiveIf specified blocks matching these identifiers will be skipped.
C++ Type:std::vector<std::string>
Controllable:No
Description:If specified blocks matching these identifiers will be skipped.
- initial_parameter1Initial guess for the parameter.
Default:1
C++ Type:Real
Unit:(no unit assumed)
Controllable:No
Description:Initial guess for the parameter.
- max_iterations50Maximum number of fixed-point iterations on the generated convergence. With method=newton each Newton update consumes two fixed-point iterations (a base and a perturbed solve), so the effective number of Newton updates is about half this value.
Default:50
C++ Type:unsigned int
Controllable:No
Description:Maximum number of fixed-point iterations on the generated convergence. With method=newton each Newton update consumes two fixed-point iterations (a base and a perturbed solve), so the effective number of Newton updates is about half this value.
- methodsecantInversion update method.
Default:secant
C++ Type:MooseEnum
Controllable:No
Description:Inversion update method.
- perturbation0.001Perturbation used to seed/compute the derivative (initial_delta for secant, parameter_delta for newton).
Default:0.001
C++ Type:Real
Unit:(no unit assumed)
Range:perturbation>0
Controllable:No
Description:Perturbation used to seed/compute the derivative (initial_delta for secant, parameter_delta for newton).
- relative_tolerance1e-06Relative tolerance on |output - target|, relative to |target|.
Default:1e-06
C++ Type:Real
Unit:(no unit assumed)
Range:relative_tolerance>0
Controllable:No
Description:Relative tolerance on |output - target|, relative to |target|.

Default:inverse_parameter
C++ Type:PostprocessorName
Unit:(no unit assumed)
Controllable:No
Description:Name of the created postprocessor holding the converged parameter (output to CSV).

Default:False
C++ Type:bool
Controllable:No
Description:Forwarded to the generated convergence: if true, it prints per-iteration convergence information, including the accept-on-max decision when accept_on_max_iterations is set.
