Limitations in application of Finite Element Method in acoustic numerical simulation
In the paper, we introduce information on limitations of the Finite Element Method in acoustic analysis. Difficulties that appear in acoustic analysis are mainly caused by the form of shape functions and sensitivities to boundaries, so we start with a short description of mathematical background. The propositions how to overcome and simplify those disadvantages are summarized and illustrated with a real application.
Keywords: applied acoustics; finite element method
