Detailed Description

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

Time-derivative interface for Partitioned IMEX RK.

Given the stage state $X_i$ and

\[ \tilde{X} = x_{n-1} +\Delta t \sum_{j=1}^{i-1} a_{ij}\,\dot{X}_{j}, \]

compute the IMEX RK stage time-derivative,

\[ \dot{X}_i = \frac{X_{i} - \tilde{X}}{a_{ii} \Delta t} \]

$\ddot{x}$ is not used and set to null.
