Krylov subspaces recycling based model order reduction for acoustic BEM systems and an error estimator

Boundary Element Method frequency sweep analyses in acoustics are usually accompanied by a vast numerical cost of assembling and solving numerous linear systems. In that context, this work proposes a model order reduction technique to mitigate the resulting computational cost of such analyses. First, a series expansion of the Green’s function BEM kernel is leveraged to construct a series of frequency independent matrices. Next, in a model order...
