What is Fluid-Structure Interaction (FSI)?
The Multiphysics study of the interactions between fluids and structures is known as fluid-structure interaction (FSI). The structure may experience pressure and/or heat loads from the fluid flow. These loads could result in structural deformation strong enough to influence fluid flow. As the degree of fluid-structure interaction grows, undesirable impacts on your product could become more pronounced. To assure safety, dependability, and lifetime, use ANSYS simulation to acquire a deeper understanding of the phenomena occurring with your product.
For every scenario involving fluid-structure interaction, ANSYS provides a variety of solutions to offer the required level of authenticity. Within ANSYS CFD, basic fluid-structure interaction issues can be fully resolved. An impeller revolving in a mixing tank provides an example of this rigid body motion.
One-way coupling, an automated, user-friendly solution from ANSYS, can be used as the fluid-structure interaction increases and the problem requires a more thorough review. One-way coupling automatically transmits and maps the data to the other system after solving the initial CFD or ANSYS Mechanical simulation. An illustration of this would be to automatically transfer the data from the fluid flow simulation around a cone flow meter to calculate the subsequent structural response.
You may utilize System Coupling to do two-way coupled FSI simulations for the most difficult and strongly linked fluid-structure interaction problems. Simultaneous setup and solution of the structural and fluid simulations. To provide reliable and accurate answers, data is automatically transmitted between the two solvers as the problem is being solved. Calculating the flow around a rigid airplane wing and transferring the pressure loads to address structural deformation would illustrate this. The structural deformation would be sent back to the CFD simulation to compute the flow once more.
The following project uses FSI to simulate the deformation of a vessel in which blood is flowing:

One of the most important applications of ANSYS software is simultaneously analyzing fluids and solids. This software allows us to use fluid-structure interactions to establish the relationship between fluid analysis and solid analysis and investigate how the structure and fluid interact. The mentioned process above is done by coupling ANSYS Fluent software with transient structural using the system coupling option in ANSYS.
With several years of experience simulating a wide range of problems in various CFD fields using ANSYS Fluent software, the MR-CFD team is ready to offer extensive modeling, meshing, and simulation services. Simulation Services for FSI are categorized as follows:
- simulation of stress and strain analysis of blood vessels in variable blood velocity
