In this work, we implement two fourth-order compact finite differences (CFD) methods and use them to model wave propagation on a elastic string. The formulation of the first method employs the standard implicit CFD constructed ...

This work studies the parallelization and empirical convergence of two finite difference acoustic wave propagation methods on 2-D rectangular grids, that use the same alternating direction implicit (ADI) time integration. ...

Acoustic metamaterials are artificially designed and manufactured structures with dy-namical properties that are not typically found in naturally-occurring materials. The design of acoustic metamaterials is considered to ...

Comparative study of Reverberation Time methods available on two acoustics simulation tools (EASE and CATT). Different aspects of the used computing routines were evaluated and the validity of the results were discussed ...

In the present work we analyze two finite difference methods for the propagation of acoustic waves proposed by Córdova et al. to optimize its performance. The computational domain is rectangular. The first of these methods ...
