Enumeration Type Documentation

enum NOX::CopyType

Specify whether to copy using deep copy or just copy by shape.

Enumerator
DeepCopy	Copy object including all data.
ShapeCopy	Copy the shape of the object only.

Function Documentation

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.

Parameters

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.
