Struct that helps to configure NOXSolver. More advanced parameters are passed to the constructor NOXSolver directly via a Teuchos::ParameterList.

unsigned int TrilinosWrappers::NOXSolver< VectorType >::AdditionalData::threshold_n_linear_iterations |
A number that indicates how many iterations a linear solver should at most perform before the preconditioner should be updated. The use of this variable is predicated on the idea that one can keep using a preconditioner built earlier as long as it is a good preconditioner for the matrix currently in use – where "good" is defined as leading to a number of iterations to solve linear systems less than the threshold given by the current variable.
This variable is only used if the NOXSolver::solve_with_jacobian_and_track_n_linear_iterations function object has been given a target (i.e., it is not empty).
