If an application interfaces their code to solvers using the EpetraExt::ModelEvaluator, this class provides a wrapper so that the model evaluator can be used instead of having the user write concrete versions of the LOCA::Epetra::Interface objects.
| bool LOCA::Epetra::ModelEvaluatorInterface::computeJacobian | ( | const Epetra_Vector & | x, | |
| Epetra_Operator & | Jac | |||
| ) | [virtual] |
Compute Jacobian given the specified input vector x. Returns true if computation was successful.
Reimplemented from NOX::Epetra::ModelEvaluatorInterface.
| void LOCA::Epetra::ModelEvaluatorInterface::setParameters | ( | const ParameterVector & | p | ) | [virtual] |
Set parameters in the user's application.
Should be called prior to calling one of the compute functions.
Implements LOCA::Epetra::Interface::Required.
| void LOCA::Epetra::ModelEvaluatorInterface::setXdot | ( | const Epetra_Vector & | xdot, | |
| const double | time | |||
| ) | [virtual] |
Routine used in XYZT to set x_dot and time in the interface.
The computeF() routine for XYZT problems needs to be a function of x_dot, but th NOX/LOCA computeF() does not take x_dot as an argument. This is used to set x_dot in the application interface so the subsequent call to computeF has the correct x_dot value. The timeStep argument is sent so the use can set the global time, for cases when computeF, computeJacobian, computeMassMatrix fills are functions of time (nonautonomous systems).
Reimplemented from LOCA::Epetra::Interface::TimeDependent.
