Member Function Documentation

◆ solveJac()

void solveJac	(	vector_Type &	_muk,
		const vector_Type &	_res,
		const Real	_linearRelTol
	)

virtual

solves the Jacobian system

The implementation of this method distinguish the various FSI formulations which derive from this class. For this reason it must be pure virtual, snd implemented in the child classes.

Parameters

muk	unknown solution at the k-th nonlinear iteration
res	residual vector (the right hand side of the Jacobian system)
linearRelTol	tolerance for the nonlinear solver

Todo:: {replace Real with Real& }

Implements FSIOperator.

Definition at line 53 of file FSIFixedPoint.cpp.

◆ evalResidual()

void evalResidual	(	vector_Type &	_res,
		const vector_Type &	_disp,
		const UInt	_iter
	)

virtual

Evaluates the nonlinear residual of the FSI system.

The implementation of this method also depends on the child classes, though it does not characterize them.

Parameters

res	residual vector to be computed
disp	current unknown solution
iter	nonlinear iteration counter. The part of th rhs related to the time discretization is computed only for iter=0

Implements FSIOperator.

Definition at line 69 of file FSIFixedPoint.cpp.

◆ setupFEspace()

void setupFEspace ( )

virtual

sets the space discretization parameters

The FE discretization is set accordingly to what specified in the FSIdata member (order of accuracy for the fluid pressure, velocity and for the structure).

Reimplemented from FSIOperator.

Definition at line 92 of file FSIFixedPoint.cpp.

◆ setupFluidSolid()

void setupFluidSolid ( void )

virtual

setup of the fluid and solid solver classes

This method computes the number of fluxes assigned at the boundaries and calls setupFluidSolid(UInt fluxes)
