Constructor & Destructor Documentation

HyperbolicLPSolver::HyperbolicLPSolver	(	const Initializer &	init,
		ParticleData *	pData,
		NeighbourSearcher *	ns
	)

Constructor.

Get and set up parameters and obtain access to objects needed for the main solver

Parameters

[in]	init	To retrieve information from init
[in]	pData	To obtain access to an object of the PaticleData clas
[in]	ns	To obtain access to an object in the NeighbourSearcher class

int HyperbolicLPSolver::solve ( double dt )

virtual

The Lagrangian particle solver for the compressible Euler's equations for one iteration step.

The method should be called by TimeController repeated at every time step

Parameters

[in] dt The length of physical time for this iteration

Warning: The function should always return 0 because all exceptions should be handled inside this class

Implements LPSolver.
