A Multiphysics Solution for Complex FSI Analyses
Fluid-structure interaction (FSI) occurs when fluid flow causes deformation of the structure. This deformation, in turn, changes the boundary conditions of the fluid flow. The animation below shows the fluid-structure interaction analysis of a membrane valve. Here, the fluid pressure deforms the membrane which changes the boundary conditions of the flow.
ADINA offers fluid-structure interaction capabilities in one single program for the solution of problems where the fluids are fully coupled to general structures that can undergo highly nonlinear response due to large deformations, inelasticity, contact and temperature-dependency. A fully coupled fluid-structure interaction means that the response of the solid is strongly affected by the response of the fluid, and vice versa.
From the fluid point of view, the Navier-Stokes flow can be incompressible, slightly compressible, low-speed or high-speed compressible. From the structural point of view, all available element types can be used (i.e. shell, 2-D and 3-D solid, beam, iso-beam, contact surfaces, etc.) as well as all available material models.
Additionally, ADINA offers very efficient fully coupled fluid-structure interaction capabilities in which the fluid is assumed to be an acoustic medium.
Direct and Iterative FSI Coupling
ADINA FSI is unique because it offers two different methods, DIRECT FSI COUPLING and ITERATIVE FSI COUPLING, to solve the coupling between the fluid and the structural models. In both cases, the conditions of displacement compatibility and traction equilibrium along the structure-fluid interfaces are satisfied:
Displacement compatibility, df = ds
Traction equilibrium, ff = fs
where d and f are displacements and tractions, and the subscripts f and s stand for fluid and solid, respectively. In transient analyses, like the simulation of the membrane valve shown above, a second-order time integration scheme can be used.
Direct FSI Coupling
In the Direct FSI Coupling solution method the fluid and solid equations are combined and treated in one system (one stiffness matrix), linearized and solved using an iterative algorithm such as the Newton-Raphson method. The Direct FSI Coupling algorithm offers great robustness when solving very difficult FSI problems, for example, large deformations with "soft" structures or highly compressible flows abutting very stiff structures. These types of problems are difficult to solve using the Iterative FSI Coupling.
Iterative FSI Coupling
The fluid and solid equations are solved individually, in succession, always using the latest information provided by the other part of the coupled system. The Iterative FSI Coupling solution method requires less memory than the Direct FSI Coupling method and therefore may be more applicable to solve very large problems.
The unique offering of the two procedures, Iterative and Direct FSI Coupling, provided by ADINA is essential to successfully solve a wide range of problems in the most efficient way.

Advanced Computational Fluid Dynamics Schemes
ADINA combines in one single program state-of-the-art computational solid and fluid dynamics schemes. For fluid flow analysis the user can choose between a nodal-based FCBI (Flow-Condition-Based Interpolation) scheme and a cell-based FCBI-C scheme.
FCBI finite element scheme: A flow-condition-based interpolation of the velocities is used to provide stability. The finite element equations are assembled calculating consistent Jacobian matrices in the Newton-Raphson iterations. Hence, consistent stiffness matrices can be established for the complete fluid-structure system which makes it possible to solve very complex practical problems with highly nonlinear response.
FCBI-C finite element scheme: All solution variables are defined in the center of the element and the coupling between the velocity and the pressure is handled iteratively. Therefore, in FSI analysis the coupling between the solid and fluid models is also handled iteratively. This scheme allows the solution of very large practical problems.
These schemes are applicable to any Reynolds number flow, from low to high Reynolds numbers.
Once any part of the computational domain deforms, the Eulerian description of the fluid flow is no longer applicable. Therefore, ADINA solves the governing equations of fluid flow using an Arbitrary-Lagrangian-Eulerian (ALE) formulation.
Key Features of ADINA FSI
- The FCBI scheme provides great stability, and is applicable to problems with both very high and very low Reynolds numbers.
- FSI analysis can be carried out with all flow types, namely incompressible, slightly compressible, low-speed compressible, and high-speed compressible flow. In addition, all fluid material models including non-Newtonian fluids, turbulence models and the VOF method are available for FSI analyses.
- In FSI analyses in which large displacements of the structure occur, ADINA provides advanced moving mesh capabilities to adequately control the mesh quality, including leader-follower constraints, slipping boundaries, and the extended wall feature. These ALE conditions ensure that the moving mesh quality is maintained in the presence of large structural deformations.
- To further increase the generality of the FSI solution capability, and the accuracy in solutions, ADINA offers the capability to adapt and repair CFD meshes so that appropriate mesh grading is used, and very large deformations of a structure can be accommodated. This adaptive meshing technique operates on CFD solution gradients and involves refining and coarsening the mesh in various regions of flow for adequate element sizes throughout the fluid region.
- Potential-based fluid elements are available for efficient FSI analysis with acoustic flows. The potential-based fluid elements may also be used to perform frequency analysis of structures interacting with acoustic flows.
- ADINA allows the use of arbitrary meshes in the fluid and solid models. Furthermore, the fluid and solid meshes do not have to match perfectly at the fluid-structure interface.
- Thermal and porous coupling is available between the fluid and the structural models.
- All structural elements, the contact capabilities and the solid material models (i.e., elastic, viscoelastic, rubber, plasticity, etc.) are available for FSI solutions.
- Gap boundary conditions can be represented in the fluid models. The gap boundary condition, combined with the contact capabilities in ADINA have been used successfully to model the opening and closing of valves in automotive and biomedical applications.
- FSI analysis with sliding-mesh capability is available. Combining sliding meshes with FSI capabilities is particularly useful to analyze rotating equipment and turbomachinery.
- An efficient option can be the automatic one-way-coupled FSI analysis. This type of analysis is very useful when deformations in the solid are small and their influence on the fluid response is negligible. Therefore, no iteration between the fluid and the solid models is needed.
