Fluid-Structure Interaction (FSI)

All fluid flows put pressure on the solid objects they interact with, which may cause deformation. In response, this deformation may affect the liquid flow around the object. By using the ANSYS multi-physics software, the interaction between these forces can be accurately calculated, thus, you can optimize the performance of your product.

The fluid and structural simulations are simultaneously generated and solved. While the solving continues, the data is automatically transmitted between the two solvers. For example, when modelling the flow around an aircraft wing the pressure forces are transmitted to the structural solver to calculate the structural deformation. The structural deformation will then be retransmitted to the CFD solver to recalculate the flow. This process will be continued until the analysis is completed.
