The aim of this work is to present a brief report concerning the various aspects of the Reduced Basis Method within Fluid-Structure Interaction problems. The idea is to adopt two different procedures and apply them to the same test case. First we preform a reduction technique that is based on a monolithic procedure, where we therefore solve all at once the fluid and the solid problem. Then we present an alternative reduction technique, that is based on a partitioned (or segregated) procedure instead: here the fluid and the solid problem are solved separately and then coupled through a fixed point strategy. The toy problem that we consider is the Turek-Hron benchmark test case, with a fluid Reynolds number Re = 100, which is known to lead to the formation of Karman vortexes in the fluid, and a periodically oscillating behaviour in the structure.
