Abstract:
In recent years, numerical methods such as the finite element method are developed for sound field prediction of architectural spaces. However, large-scale analysis is often necessary because of the larger domains and the higher frequencies that we deal with in engineering applications. Therefore, we often only consider larger domains at low frequencies or high frequencies in smaller domains. In this paper, the iterative domain decomposition method (IDDM) is applied to solve transient and steady-state acoustic problems. By applying the IDDM, the effectiveness of the large-scale acoustic analysis can be shown. In addition, the results of introducing high-order elements into the analysis are shown.
