Detailed Description

template<class Scalar>
class Tempus::StepperRKModifierXBase< Scalar >

Base ModifierX for StepperRK.

This class provides a means to modify just the solution values (i.e., $x$ and $dot{x}$ ), and nothing else, but time and timestep are also provided.

Users deriving from this class can access and change the solution during the timestep (e.g., limiting the solution for monoticity). It is expected that the user knows what changes are allowable without affecting the Stepper correctness, performance, accuracy and stability (i.e., USER BEWARE!!).

The locations of the StepperRKModifierXBase::MODIFIER_TYPE which correspond to the RK AppActions (StepperRKAppAction::ACTION_LOCATION) in takeStep are documented in each of the RK Algorithm sections: StepperExplicitRK, StepperDIRK and StepperIMEX_RK.
