Overview of Fluid-Structure Interaction Interfaces
The Model Wizard and the Add Physics window contain a number of multiphysics interfaces for modeling fluid-structure interaction (FSI), all available under the Fluid-Structure Interaction branch (). The multiphysics interfaces for FSI are described in the subsequent sections:
The Fluid-Solid Interaction Interface: For fluid-structure interaction between a fluid and a solid.
The Fluid-Solid Interaction, Fixed Geometry Interface: For fluid-structure interaction between a fluid and a solid where the displacements of the solid are assumed to be small enough for the geometry of the fluid domain to be considered as fixed during the interaction.
The Fluid-Shell Interaction Interface: For fluid-structure interaction between a fluid and a shell structure.
The Fluid-Shell Interaction, Fixed Geometry Interface: For fluid-structure interaction between a fluid and a shell structure where the displacements of the shell are assumed to be small enough for the geometry of the fluid domain to be considered as fixed during the interaction.
The Fluid-Membrane Interaction Interface: For fluid-structure interaction between a fluid and a membrane structure.
The Fluid-Membrane Interaction, Fixed Geometry Interface: For fluid-structure interaction between a fluid and a membrane structure where the displacements of the membrane are assumed to be small enough for the geometry of the fluid domain to be considered as fixed during the interaction.
The Fluid-Pipe Interaction, Fixed Geometry Interface: This multiphysics interface provides a connection between the Pipe Flow interface and the Pipe Mechanics interface. The coupling is unidirectional, so that various types of loads from the fluid loads can be transferred to structural analysis.
The Solid Thin-Film Damping Interface: For fluid-structure interaction between a thin-film fluid and a solid under isothermal conditions.
The Shell Thin-Film Damping Interface: For fluid-structure interaction between a thin-film fluid and a shell under isothermal conditions.
The Fluid-Multibody Interaction Interface: For fluid-structure interaction between a fluid and mechanical parts. See Multiphysics Couplings in the Multibody Dynamics Module User’s Guide.
The Fluid-Multibody Interaction, Assembly Interface: For fluid-structure interaction between a fluid and mechanical parts. An ALE formulation is used for incorporating the geometrical changes of the fluid domain. See Multiphysics Couplings in the Multibody Dynamics Module User’s Guide.
The Fluid-Solid Interaction, Conjugate Heat Transfer Interface: For fluid-structure interaction between a fluid and a solid under nonisothermal conditions.
The Fluid-Solid Interaction, Two-Phase Flow, Phase Field Interface: For fluid-structure interaction between two immiscible fluids and a deformable solid. An ALE formulation is used for incorporating the geometrical changes of the fluid domain. The interface between the two fluids is tracked by the phase field method.
The Fluid-Solid Interaction, Two-Phase Flow, Phase Field, Fixed Geometry Interface: For fluid-structure interaction between two immiscible fluids and a solid where the displacements of the solid are assumed to be small enough to be considered as fixed during the interaction.
