Detailed Description

Class AitkenConvergenceAccelerator.

This class contains the implementation of Aitken relaxation and helper functions. Reference: Ulrich Küttler et al., "Fixed-point fluid–structure interaction solvers with dynamic relaxation"

Constructor & Destructor Documentation

◆ init()

def convergence_accelerators.aitken.AitkenConvergenceAccelerator.__init__	(	self,
		settings
	)

The constructor.

Parameters

init_alpha	Initial relaxation factor in the first time step.
init_alpha_max	Maximum relaxation factor for the first iteration in each time step

◆ UpdateSolution()

def convergence_accelerators.aitken.AitkenConvergenceAccelerator.UpdateSolution	(	self,
		r,
		x
	)

UpdateSolution(r, x)

Parameters

r	residual r_k
