This work is focused on the exchange of information between two domains in fluid-structure
interaction (FSI) context. Most concretely, in the case when the structure domain is mod-
elled with 3D beam elements.
The MappingApplication of the open-source framework Kratos Multi-Physics was ex-
tended. This was done with the implementation of a mapping algorithm for beam elements.
This is needed because beam structures can be often simplified using beam elements. In
this case, as no geometrically matching interface exists, the relation between the beam
elements and a fluid surface mesh has to be determined.
In the introduction, the motivation of this work is presented. Furthermore, an overview of
mapping theory and the mapping algorithm for beam elements is given. Two approaches
are considered for the mapping of deformations: a linear and a co-rotating algorithm.
After an overview of the current state of MappingApplication, both approaches and the
mapping of forces are implemented. The implementation is tested and validated with the
literature and two FSI simulations in different dimensions are shown.
Finally, the conclusions and further improvements for the implementation are given, iden-
tifying also its limitations.
