Detailed Description

template<class Scalar>
class VanDerPol_ModelEvaluator_02< Scalar >

ModelEvaluator implementation for the example van der Pol Problem.

This is a trimmed down version of the ModelEvaluator used in Tempus testing, Tempus_Test::VanDerPolModel, which exercises additional functionalities. In this ModelEvaluator, we are just trying to demonstrate the mechanisms needed for the simple time integration, e.g., explicit and implicit ODEs for the van der Pol Problem.

Constructor & Destructor Documentation

template<class Scalar >
VanDerPol_ModelEvaluator_02< Scalar >::VanDerPol_ModelEvaluator_02 ( )

Default Constructor sets the van der Pol Problem

  • parameter ( $\epsilon=0.1$ )
  • the inital time ( $t_0=0$ )
  • the initial conditions ( $x_0(t_0=0) = 2$, $x_1(t_0=0) = 0$, $\dot{x}_0(t_0=0) = 0$, and $\dot{x}_1(t_0=0) = -2/\epsilon$ )

constructs

  • the solution vector space (a defaultSpmdVectorSpace of dimension 2)
  • the function evaluation vector space (a defaultSpmdVectorSpace of dimension 2)
  • a prototypical InArgs that just supports
    • the time (IN_ARGS_t)
    • the solution vector (IN_ARGS_x)
    • the time derivative of the solution vector (IN_ARGS_x_dot)
  • a prototypical OutArgs that just supports
    • the evaluation vector (OUT_ARG_f)
  • the nominal values (a.k.a. initial conditions for transient problems)
    • simply the prototypical InArgs with the initial condition vectors

private

Evaluate the model based on if the InArgs.get_x_dot() is null or not. If it is null, evaluate the explicit ODE form of the model ( $ \dot{x} = f(x,t)$ ),

\begin{eqnarray*} \dot{x}_0(t) & = & f_0 = x_1(t) \\ \dot{x}_1(t) & = & f_1 = [(1-x_0^2)x_1-x_0]/\epsilon \end{eqnarray*}

otherwise, evaluate the implicit ODE form, $ \mathcal{F}(\dot{x},x,t) = 0 $,

\begin{eqnarray*} \mathcal{F}_0 & = & \dot{x}_0(t) - x_1(t) \\ \mathcal{F}_1 & = & \dot{x}_1(t) - [(1-x_0^2)x_1-x_0]/\epsilon \end{eqnarray*}

Both return their result through the OutArgs.get_f().
