To predict the sound radiation of structures, both a structural problem and an acoustic
problem have to be solved. In case of thin structures and dense fluids, a strong coupling …

High intensity focused ultrasound (HIFU) enables highly localized, non-invasive tissue
ablation and its efficacy has been demonstrated in the treatment of a range of cancers …

Conventional element based methods for modelling structural-acoustic radiation problems
are limited to low-frequency applications. Recently, a novel prediction technique has been …

The Fast Multipole Boundary Element Method (FMBEM) reduces the O (N 2) computational
and memory complexity of the conventional BEM discretized with N boundary unknowns, to …

The goal of the thesis is to provide an efficient simulation tool for the prediction of sound
radiation from vibrating structures. Acoustic simulations are an important step to optimize the …

The efficacy of high-intensity focused ultrasound (HIFU) for the treatment of a range of
different cancers, including those of the liver, prostate and breast, has been demonstrated …

Fluid–structure coupled problems are investigated to predict the vibro‐acoustic behavior of
submerged bodies. The finite element method is applied for the structural part, whereas the …

The non-negative intensity (NNI) method is applied to large-scale coupled fluid–structure
interaction (FSI) problems using the fast multipole boundary element method (FMBEM). The …

Die numerische Akustik hat sich in den letzten Jahren parallel mit der schnell steigenden
Leistungsfähigkeit der Computer rasant weiterentwickelt und durchdringt nahezu alle …

There are verities of useful Krylov subspace methods to solve nonsymmetric linear system of
equations. GMRES is one of the best Krylov solvers with several different variants to solve …
