Coupling water and smoke to thin deformable and rigid shells (2005, methodology): “For compressible fluids, one typically uses the pressure to provide a force on the surface of the solid, but for incompressible flow the pressure can be both stiff and noisy as compared to the velocity field, as discussed in [Fedkiw 2002].”
An interface interaction method for compressible multifluids (2004, methodology): “As will be shown in this paper, SFM encounters essentially the same difficulties as the GFM. Fedkiw (2002) presented a modified GFM for the air-water interaction which eliminates the oscillations at the air-water interface.”
Ghost fluid method for strong shock impacting on material interface (2003, methodology): “Fedkiw [15], therefore, proposed a new version of GFM, which may overcome the difficulty encountered by the original GFM used for the gas–water flow and also those problems associated with the shock impact on the gas–water interface like Cases 3 and 4 to be presented in Section 4.”
Optimal transportation meshfree approximation schemes for fluid and plastic flows (2010, methodology): “A number of strategies have been devised with a view to overcoming these difficulties, including: Particle methods such as smooth particle hydrodynamics [1–3]; ghost fluid and immersed boundary methods [4–8]; the material-point method [9–13]; Lagrangian formulations with continuous adaptive remeshin”
A level set approach to Eulerian-Lagrangian coupling (2003, methodology): “Throughout this paper, we will use the sign convention introduced in [9],”
Spatially adaptive techniques for level set methods and incompressible flow (2006, methodology): “This methodology is the " workhorse " behind the Department of Energy ASCI center at Caltech for studying solid fluid interactions, see e.g. [32] [5] [4].”
A sharp interface immersed boundary method for compressible viscous flows (2007, result): “It is useful to compare and contrast the current approach with the ‘‘ghost-fluid method’’ of Fedkiw and coworkers [35,12], since this method also employs ghost-nodes in order to close the discretized system of equations.”
A ghost-cell immersed boundary method for flow in complex geometry (2002, methodology): “The ghost cell method is very popular for treating two-phase flows, obtaining accurate discretization across the interface [9,10,45].”
A review of level-set methods and some recent applications (2018, methodology): “It has also been applied to the coupling of Eulerian/Lagrangian frameworks [101] and compressible/incompressible flows [102].”
The ghost fluid method for compressible gas-water simulation (2005, methodology): “This has led to a better performance of the latter in applications to gas–water flow [13].”
