URANS–FSI Case Files for Axial Flow-Induced Vibration of a Cantilever Rod for Nuclear Application

This repository contains the input files, setup scripts, and documentation for the URANS–FSI simulation framework developed during the author’s PhD at the University of Manchester. The case models the axial flow-induced vibration (FIV) of a blunt-ended cantilevered rod in turbulent axial flow using an unsteady Reynolds-averaged Navier–Stokes (URANS) turbulence model coupled with a structural solver through two-way fluid–structure interaction (FSI).

The data are intended to support reproducibility and benchmarking of future FSI research in nuclear and energy applications.
