Research output: Contribution to journalArticlepeer-review


A multiphase fluid-structure interaction (FSI) framework using open-source software has been developed, utilising components able to run on high-performance computing platforms. A partitioned approach is employed, ensuring a separation of concerns (fluid, structure, and coupling), allowing design flexibility and robustness while reducing future maintenance effort. Multiphase FSI test cases have been simulated and compared with published results and show good agreement. This demonstrates the ability of this multiphase FSI framework in simulating complex and challenging cases involving a free liquid surface.
