Abstract:
Models for Fluid Structure Interaction (FSI) in room acoustical calculations are used in many different fields of engineering like automotive industry or civil engineering. In order to obtain the sound field within an acoustic cavity, which is covered by absorptive boundary structures, with its spatial distribution, very often techniques based on Finite Element formulations are used instead of energy methods. In order to reduce the number of degrees of freedom and therefore the numerical effo...     »
