Detailed Description

template<class Scalar>
class Tempus::StepperObserver< Scalar >

StepperObserver class for Stepper class.

This is a means for application developers to perform tasks during the time steps, e.g.,

  • Compute specific quantities
  • Output information
  • "Massage" the working solution state
  • ...

Design Considerations

  • This base class only requires two functions, observeBeginTakeStep() and observeEndTakeStep() as these are the only ones that all Steppers have in common.
  • StepperObserver is not stateless! Developers may touch the solution state! Developers need to be careful not to break the restart (checkpoint) capability.
