Detailed Description

template<typename Scalar>
class Tempus::TimeDerivative< Scalar >

This interface defines the time derivative connection between an implicit Stepper and WrapperModelEvaluator.

For a WrapperModelEvaluator which uses an implicit Stepper, i.e., uses the implicit ODE or DAE form, $\mathcal{F}(\ddot{x},\dot{x},x,t)$ , requires definition of the time derivatives during the iterations of the nonlinear solve. Note that if the Stepper solves for a time derivative, e.g., $\ddot{x}$ for the Newmark- $\beta$ methods, definitions for $x$ and $\dot{x}$ are required in the function compute(). This interface defines the calling function to compute those derivatives and/or state.
