"Fulfills the need for an introductive approach to the general concepts of FSI from
the mathematical formulation to the physical interpretation of numerical simulations.
Based on the author's experience in developing numerical codes for industrial applications
in shipbuilding and in teaching FSI to both practicing engineers and within academia,
it provides a comprehensive and self-contained guide that is geared toward both students
and practitioners of mechanical engineering"
