We introduce and analyze a new finite element method for a three-dimensional fluidsolid interaction problem. The media are governed by the acoustic and elastodynamic equations in a time-harmonic ...

But solving fluidstructure and fluidthermal problems with older FEA codes requires solving the fluid part and somehow mapping its results onto the other. Analysts might also have to tweak the mesh to ...

We analyze the approximation of a vibro-acoustic eigenvalue problem for an elastic body which is submerged in a compressible inviscid fluid in ℝ3. As a model, the time-harmonic elastodynamic and the ...
