Understanding FSI: A Weakly Coupled Case with Ansys
This educational resource introduces the fundamentals of Fluid–Structure Interaction (FSI) through a practical, weakly coupled (one‑way) simulation workflow using both Ansys Mechanical™ structural finite element analysis software and Ansys Fluent® fluid simulation software within the Ansys Workbench™ simulation integration platform. Learners explore how fluid‑induced pressures obtained from a steady‑state CFD analysis can be transferred to a structural model to evaluate deformation and stress response. Emphasis is placed on understanding multiphysics concepts, and data transfer rather than application‑specific complexity. This resource is ideal for students and educators seeking a clear introduction to FSI workflows and physics‑based loading strategies, serving as a strong foundation for progressing toward advanced multiphysics and fully coupled analyses.
Learning Outcomes
- Explain the principles, assumptions, and applicability of weakly coupled Fluid–Structure Interaction analysis.
- Set up and execute a one‑way FSI workflow in Ansys using CFD‑derived pressure loads.
