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

Modular vs. non-modular preconditioners for fluid-structure systems with large added-mass effect (2008, methodology): “Examples of semi-implicit algorithms can be found in [ 13 , 4]. Semi-implicit methods treat explicitly nonlinearity (reducing CPU cost) and implicitly the fluid-structure coupling (keeping stability).”
Solvers for large-displacement fluid–structure interaction problems: segregated versus monolithic approaches (2008, background): “It is also believed to be “difficult to devise efficient global preconditioners and to maintain stateof-the-art schemes in each solver” [2] when a monolithic solver is used.”
A convergence study of a new partitioned fluid-structure interaction algorithm based on fictitious mass and damping (2012, unknown): “proposed a semi-implicit coupling scheme based on the pressure correction method where only the pressure is coupled with the structure while nonlinear and viscous terms are updated explicitly [17].”
