Detailed Description

This class solves the fully implicit black-oil system by applying a Constrained Pressure Residual preconditioning strategy. The approach is similar to the one described in "Preconditioning for Efficiently Applying Algebraic Multigrid in Fully Implicit Reservoir Simulations" by Gries et al (SPE 163608).

Member Typedef Documentation

typedef LinearisedBlackoilResidual::ADB::V Opm::NewtonIterationBlackoilInterface::SolutionVector

inherited

Return type for linearSolve(). A simple, non-ad vector type.

Constructor & Destructor Documentation

Opm::NewtonIterationBlackoilCPR::NewtonIterationBlackoilCPR	(	const parameter::ParameterGroup &	param,
		const boost::any &	parallelInformation = boost::any()
	)

Construct a system solver.

Parameters

[in]	param	parameters controlling the behaviour of the preconditioning and choice of linear solvers. Parameters: cpr_relax (default 1.0) relaxation for the preconditioner cpr_ilu_n (default 0) use ILU(n) for preconditioning of the linear system cpr_use_amg (default false) if true, use AMG preconditioner for elliptic part cpr_use_bicgstab (default true) if true, use BiCGStab (else use CG) for elliptic part
[in]	parallelInformation	In the case of a parallel run with dune-istl the information about the parallelization.
