Models and tutorials and stuff for Comsol. Files to help work with the program COMSOL Multiphysics.Year: 2011Producer and writer: COMSOLLanguage: EnglishThis note is devoted to a domain decomposition method solvingthe Helmholtz equation in the frequency domain. This is meant forcomputing the acoustic profile of a cavity when forced at a given fre-quency k. This profile depends, of course , on the global geometry ofthe cavity, that we call here domain and denote it by Ω. Let a par-tition of the cavity Ω be given, as a union of disjoint subsets, calledsubdomains: Ω = ∪Ωi. We need to perform this global computa-tion as a sequence of local computations, each computation beeingperformed on a single subdomain Ωi, without any knowledge of thegeometry...
