Member Function Documentation

solveLinearSys() [1/2]

Eigen::MatrixXd reducedProblem::solveLinearSys ( List< Eigen::MatrixXd > LinSys, Eigen::MatrixXd x, Eigen::VectorXd & residual, const Eigen::MatrixXd & bc = Eigen::MatrixXd::Zero(0,                                                  0), const std::string solverType = "fullPivLu" )

static

Linear system solver for the online problem.

It can be used for any kind of variable. Boundary conditions are set to 0 as default so that the system is not constrained if no conditions are given (pressure case). The solver has to be choosen between Eigen linear solvers (fullPivLu set as default).

Parameters

[in]	LinSys	The linear system as a list of matrices.
[in]	x	Solution of the problem at previous step.
	residual	Residual given to let the function update it.
[in]	bc	Boundary conditions to constrain the system.
[in]	solverType	Solver type.

Returns

Updated solution to the system.
