ChainControls System

The ChainControls system is an extension of the Controls system that uses ChainControl objects, which instead of working directly with controllable parameters, work with an additional layer of "control data", ChainControlData. ChainControl objects can do the following:

• Declare new control data

• Retrieve control data declared elsewhere

• Change control data values

• Set controllable parameters in MOOSE objects using control data

The main advantage of this additional capability is to chain control operations together, which is useful for composing complex control systems.

ChainControlData is managed by the ChainControlDataSystem.
