Detailed Description

This is an iterative LCP solver that can be used when multiple processes are using ChLcpSystemDescriptorMPI that can communicate via MPI. Hence, the solution comes from a Schwarz alternating method.

Constructor & Destructor Documentation

chrono::ChLcpIterativeSchwarzMPI::ChLcpIterativeSchwarzMPI	(	int	mdomain_iters = 10,
		int	minner_iters = 20,
		bool	mwarm_start = false,
		double	mtolerance = 0.0,
		double	momega = 1.0
	)

Parameters:

mdomain_iters	number of outer iterations (Schwarz inter-domain updates)
minner_iters	number of inner domain solver iterations
mwarm_start	uses warm start?
mtolerance	tolerance for termination criterion
momega	overrelaxation criterion

Member Function Documentation

double chrono::ChLcpIterativeSchwarzMPI::Solve	(	ChLcpSystemDescriptor &	sysd,
		bool	add_Mq_to_f = false
	)		[virtual]

Performs the solution of the LCP.

Returns:

the maximum constraint violation after termination.

Parameters:

sysd	system description with constraints and variables
add_Mq_to_f	if true, takes the initial 'q' and adds [M]*q to 'f' vector

Implements chrono::ChLcpSolver.
