The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

OpenMDAO: an open-source framework for multidisciplinary design, analysis, and optimization (2019, methodology): “The coupled analysis method that is easiest to implement is a fixed-point iteration (also known as nonlinear block Gauss– Seidel iteration), but for strongly coupled models, Newtontype methods are potentially more efficient [40, 44, 58, 15].”
Isogeometric fluid-structure interaction: theory, algorithms, and computations (2008, background): “However, recent attempts have been made to design schemes that could in principle use existing fluid and structure software in the context of fully-coupled approaches [ 24 ].”
Truly monolithic algebraic multigrid for fluid–structure interaction (2011, methodology): “The Newton–Krylov scheme with block preconditioning to solve the FSI problem (16) has been introduced in [18, 28].”
Partitioned solver for strongly coupled fluid–structure interaction (2013, background): “are solved simultaneously and are discretized in time and space in the same manner [7–11].”
A convergence study of a new partitioned fluid-structure interaction algorithm based on fictitious mass and damping (2012, background): “The scalability and preconditioning of a single large system of the monolithic scheme have been investigated in [8,4,9].”
