void NOX::ObserverLog::runPostSolutionUpdate ( const NOX::Solver::Generic & )

virtual

User defined method that will be executed after the update of the solution vector during a call to NOX::Solver::Generic::step(). This is intended to allow users to adjust the direction after the solution update, typically based on knowledge of the problem formulation (e.g. clipping negative mass fractions). The direction is const as we can't guarantee that changes to the direction won't violate assumptions of the solution algorithm. Users can change the update/direciton after a const cast, but NOX may not function as expected. Use at your own risk!

Parameters

[in] solver - the nox solver

Reimplemented from NOX::Observer.

void NOX::ObserverLog::runPreSolutionUpdate	(	const NOX::Abstract::Vector &	,
		const NOX::Solver::Generic &
	)

virtual

User defined method that will be executed prior to the update of the solution vector during a call to NOX::Solver::Generic::step(). This is intended to allow users to adjust the direction before the solution update, typically based on knowledge of the problem formulation. The direction is const as we can't guarantee that changes to the direction won't violate assumptions of the solution algorithm. Users can change the update/direciton after a const cast, but NOX may not function as expected. Use at your own risk!

Parameters

[in]	update	- the direction vector that will be used to update the solution.
[in]	solver	- the nox solver

Reimplemented from NOX::Observer.
