Constructor & Destructor Documentation

DefaultTimeController::DefaultTimeController	(	const Initializer &	init,
		LPSolver *	solver,
		const std::vector< ParticleViewer * > &	viewers
	)

Constructor.

The constructor initializes parameters based on and also initializes the main solver and viewer based on solver and used to perform the main iterations and to write results for viewing

Parameters

[in]	init	Const reference to an object of the Initializer class
[in]	solver	Pointer to an object of the LPSolver family
[in]	viewers	Vector containing pointers to objects of the ParticleViewer family

Member Function Documentation

int DefaultTimeController::solve ( )

virtual

Calls main solvers of the simulation and determines the time stepping between iterations.

The simulation is performed by calling the main LP solver for each iteration and the time length between iterations is determined by the CFL condition

Parameters

None

Returns

0 if the entire simulation runs successfully to the end; 1 if main solver fails during any iteration

Implements TimeController.
