The goal of this master thesis was to develop and implement the embedded domain method for use in partitioned fluid-structure interaction scenarios. This approach greatly simplifies FSI problems, as it decouples the fluid from the structural mesh, avoiding the problems that arise from body-fitting methods. To this end, the Kratos Multiphysics framework using an embedded CFD solver was used. The embedded approach was tested against the body-fitted ALE approach.
The method was used in conjunction with isogeometric analysis lightweight structures, and a mapper between isogeometric finite elements and classical finite elements or finite volumes, within the framework of the EMPIRE coupling software suite, was further developed. This new -in the context of the EMPIRE suite- mapper utilizes a barycentric approach, based on point-to-surface projections, to exchange data fields between the fluid and structure solvers. It was afterwards validated against existing mappers that utilize a mortar based approach, for both isogeometric and classical finite elements.
