Detailed Description

template<class Scalar>
class Tempus::StepperImplicit< Scalar >

Thyra Base interface for implicit time steppers.

For first-order ODEs, we can write the implicit ODE as

\[ \mathcal{F}(\dot{x}_n,x_n,t_n) = 0 \]

where $x_n$ is the solution vector, $\dot{x}$ is the time derivative, $t_n$ is the time and $n$ indicates the $n^{th}$ time level. Note that $\dot{x}_n$ is different for each time stepper and is a function of other solution states, e.g., for Backward Euler,

\[ \dot{x}_n(x_n) = \frac{x_n - x_{n-1}}{\Delta t} \]

Defining the Iteration Matrix

Often we use Newton's method or one of its variations to solve for $x_n$, such as

\[ \left[ \frac{\partial}{\partial x_n} \left( \mathcal{F}(\dot{x}_n,x_n,t_n) \right) \right] \Delta x_n^\nu = - \mathcal{F}(\dot{x}_n^\nu,x_n^\nu,t_n) \]

where $\Delta x_n^\nu = x_n^{\nu+1} - x_n^\nu$ and $\nu$ is the iteration index. Using the chain rule for a function with multiple variables, we can write

\[ \left[ \frac{\partial \dot{x}_n(x_n) }{\partial x_n} \frac{\partial}{\partial \dot{x}_n} \left( \mathcal{F}(\dot{x}_n,x_n,t_n) \right) + \frac{\partial x_n}{\partial x_n} \frac{\partial}{\partial x_n} \left( \mathcal{F}(\dot{x}_n,x_n,t_n) \right) \right] \Delta x_n^\nu = - \mathcal{F}(\dot{x}_n^\nu,x_n^\nu,t_n) \]

Defining the iteration matrix, $W$, we have

\[ W \Delta x_n^\nu = - \mathcal{F}(\dot{x}_n^\nu,x_n^\nu,t_n) \]

using $\mathcal{F}_n = \mathcal{F}(\dot{x}_n,x_n,t_n)$, where

\[ W = \alpha \frac{\partial \mathcal{F}_n}{\partial \dot{x}_n} + \beta \frac{\partial \mathcal{F}_n}{\partial x_n} \]

and

\[ W = \alpha M + \beta J \]

where

\[ \alpha \equiv \frac{\partial \dot{x}_n(x_n) }{\partial x_n}, \quad \quad \beta \equiv \frac{\partial x_n}{\partial x_n} = 1, \quad \quad M = \frac{\partial \mathcal{F}_n}{\partial \dot{x}_n}, \quad \quad J = \frac{\partial \mathcal{F}_n}{\partial x_n} \]

and $M$ is the mass matrix and $J$ is the Jacobian.

Note that sometimes it is helpful to set $\alpha=0$ and $\beta = 1$ to obtain the Jacobian, $J$, from the iteration matrix (i.e., ModelEvaluator), or set $\alpha=1$ and $\beta = 0$ to obtain the mass matrix, $M$, from the iteration matrix (i.e., the ModelEvaluator).

As a concrete example, the time derivative for Backward Euler is

\[ \dot{x}_n(x_n) = \frac{x_n - x_{n-1}}{\Delta t} \]

thus

\[ \alpha \equiv \frac{\partial \dot{x}_n(x_n) }{\partial x_n} = \frac{1}{\Delta t} \quad \quad \beta \equiv \frac{\partial x_n}{\partial x_n} = 1 \]

and the iteration matrix for Backward Euler is

\[ W = \frac{1}{\Delta t} \frac{\partial \mathcal{F}_n}{\partial \dot{x}_n} + \frac{\partial \mathcal{F}_n}{\partial x_n} \]

Dangers of multiplying through by $\Delta t$. In some time-integration schemes, the application might want to multiply the governing equations by the time-step size, $\Delta t$, for scaling or other reasons. Here we illustrate what that means and the complications that follow from it.

Starting with a simple implicit ODE and multiplying through by $\Delta t$, we have

\[ \mathcal{F}_n = \Delta t \dot{x}_n - \Delta t \bar{f}(x_n,t_n) = 0 \]

For the Backward Euler stepper, we recall from above that

\[ \dot{x}_n(x_n) = \frac{x_n - x_{n-1}}{\Delta t} \quad\quad \alpha \equiv \frac{\partial \dot{x}_n(x_n) }{\partial x_n} = \frac{1}{\Delta t} \quad \quad \beta \equiv \frac{\partial x_n}{\partial x_n} = 1 \]

and we can find for our simple implicit ODE, $\mathcal{F}_n$,

\[ M = \frac{\partial \mathcal{F}_n}{\partial \dot{x}_n} = \Delta t, \quad \quad J = \frac{\partial \mathcal{F}_n}{\partial x_n} = -\Delta t \frac{\partial \bar{f}_n}{\partial x_n} \]

Thus this iteration matrix, $W^\ast$, is

\[ W^\ast = \alpha \frac{\partial \mathcal{F}_n}{\partial \dot{x}_n} + \beta \frac{\partial \mathcal{F}_n}{\partial x_n} = \frac{1}{\Delta t} \Delta t + (1) \left( - \Delta t \frac{\partial \bar{f}_n}{\partial x_n} \right) \]

or simply

\[ W^\ast = 1 - \Delta t \frac{\partial \bar{f}_n}{\partial x_n} \]

Note that $W^\ast$ is not the same as $W$ from above (i.e., $W = \frac{1}{\Delta t} - \frac{\partial \bar{f}_n}{\partial x_n}$). But we should not infer from this is that $\alpha = 1$ or $\beta = -\Delta t$, as those definitions are unchanged (i.e., $\alpha \equiv \frac{\partial \dot{x}_n(x_n)} {\partial x_n} = \frac{1}{\Delta t}$ and $\beta \equiv \frac{\partial x_n}{\partial x_n} = 1 $). However, the mass matrix, $M$, the Jacobian, $J$ and the residual, $-\mathcal{F}_n$, all need to include $\Delta t$ in their evaluations (i.e., be included in the ModelEvaluator return values for these terms).

Dangers of explicitly including time-derivative definition. If we explicitly include the time-derivative defintion for Backward Euler, we find for our simple implicit ODE,

\[ \mathcal{F}_n = \frac{x_n - x_{n-1}}{\Delta t} - \bar{f}(x_n,t_n) = 0 \]

that the iteration matrix is

\[ W^{\ast\ast} = \alpha \frac{\partial \mathcal{F}_n}{\partial \dot{x}_n} + \beta \frac{\partial \mathcal{F}_n}{\partial x_n} = \frac{1}{\Delta t} (0) + (1) \left(\frac{1}{\Delta t} - \frac{\partial \bar{f}_n}{\partial x_n} \right) \]

or simply

\[ W^{\ast\ast} = \frac{1}{\Delta t} - \frac{\partial \bar{f}_n}{\partial x_n} \]

which is the same as $W$ from above for Backward Euler, but again we should not infer that $\alpha = \frac{1}{\Delta t}$ or $\beta = -1$. However the major drawback is the mass matrix, $M$, the Jacobian, $J$, and the residual, $-\mathcal{F}_n$ (i.e., the ModelEvaluator) are explicitly written only for Backward Euler. The application would need to write separate ModelEvaluators for each stepper, thus destroying the ability to re-use the ModelEvaluator with any stepper.
