Permanent fluid–structure interaction with non-conforming interfaces in fast transient dynamics Original Research Article

This paper presents the extension to the case of non-conforming interfaces of a family of fluid–structure interaction (FSI) algorithms originally based upon the hypothesis of nodally conforming fluid and structure finite element (or finite volume) meshes along their interface. The algorithms are implemented in the EUROPLEXUS system for fast transient dynamics analysis and their efficiency is shown on various examples, including an industrial application dealing with rapid depressurisation of the HDR test facility under hypothetical LOCA conditions.
