This paper illustrates the use of the open-source code MultiFEBE for the numerical solution of different structural dynamics and wave propagation problems that lend themselves to be solved by mixed-dimensional models coupling boundary elements and finite elements. MultiFEBE, developed in the University Institute for Intelligent Systems and Numerical Applications in Engineering (SIANI) of the University of Las Palmas de Gran Canaria [1], allows the time-harmonic analysis of problems coupling wave propagation in continuum media (acoustics, elastodynamics, and poroelastodynamics) and structural dynamics (discrete, beams and shells) [2,3]. The presented case studies include an analysis of the seismic response of the Soria arch dam including the surrounding media, the study of the seismic response of a jacket-based offshore wind turbine including soil-structure interaction, and an analysis of the efficiency of acoustic noise barriers.
