| Teuchos::RCP< NOX::Observer > | createReusePreconditionerObserver (Teuchos::ParameterList &pl) |
Nonlinear solvers package namespace.
| enum NOX::CopyType |
| Teuchos::RCP< NOX::Observer > NOX::createReusePreconditionerObserver | ( | Teuchos::ParameterList & | pl | ) |
Non-member function to create an observer that will reuse the preconditioner across multiple linear solves and time steps.
When to update the preconditioner is controlled by the ParameterList arguments below.
| Update prec at start of nonlinear solve | (bool) Update preconditioner at the start of each nonlinear solve. Defaults to true. |
| Update prec after this many nonlinear iterations | (int) Update preconditioner after this many nonlinear iterations. Setting to 0 disables. Defaults to 0 (disabled). |
| Update prec after this many stalled linear solves | (int) Update prec after this many stalled linear solves. Setting to 0 disables. Defaults to 0 (disabled). |
| Max linear iterations for stall | (int) Maximum number of linear iterations that triggers a nonlinear iteration to be declared stalled. Defaults to 50. |
