Detailed Description

Nonlinear, stochastic Galerkin ModelEvaluator.

SGModelEvaluator is an implementation of EpetraExt::ModelEvaluator that generates a nonlinear problem from a stochastic Galerkin expansion. It wraps a supplied ModelEvaluator that supports the SG versions of p, x, and possibly x_dot InArgs, and f and W OutArgs, and translates those into a new nonlinear problem. It does so by concatenating all of the SG components of p, x, x_dot, and f into extended block vectors that form the parameters, solution vector, time derivative vector and residual for the new nonlinear problem. For dealing with the W matrix two methods are supported: forming a fully-assembled SG matrix and a "matrix free" method. The choice is selected by setting the "Jacobian Method" parameter of the parameter list supplied to the constructor, which can be either "Fully Assembled" or "Matrix Free". In the first case, the W operator of the underlying model evaluator must be an Epetra_CrsMatrix. In the second case, a preconditioner for the mean block must also be supplied via the "Preconditioner Factory" parameter of this list. This preconditioner factory must implement the Stokhos::PreconditionerFactory interface also supplied in this file. Currently using a preconditioner for the mean is the only option available for preconditioning the SG system when using the matrix-free method.
