Detailed Description

template<class Scalar>
class Tempus::Integrator< Scalar >

Thyra Base interface for time integrators. Time integrators are designed to advance the solution from an initial time, $t_0$ , to a final time, $t_f$ .

Design Considerations

Integrators manage multiple time steps
Integrators have a single Stepper
Time-step ramping and startup are handled by TimeStepControl.
Solution output, e.g., solution plotting and check pointing, is coordinated in the Integrator.
Solution stability is handled in the timeStepControl, e.g., CFL constraint.
Error control over multiple time steps is handled in the Integrators, while error control over a single time step is handled in the Steppers.
Integrators will collect error control information from the Stepper and determine the next time step size and order.
Integrator maintains its own copy of the time history in the SolutionHistory, which may be just a single time step up to the entire solution history.
Integrators should compute the next time, and after accepting the time step advance the solution. This allows a simple undo capability, if a solution is not acceptable.

CS Design Considerations

Integrators will be fully constructed with input or default parameters.
All input parameters (i.e., ParameterList) can be set by public methods.
The Integrator ParameterList must be consistent.
- The "set" methods which update parameters in the ParameterList must update the Integrator ParameterList.
