Development of general-purpose open source package for multiphysical acoustic numerical simulations

本研究开发了多物理场声学数值模拟通用软件包及其相应的预处理和后处理接口，并努力将结果在网络上开放。研究的多物理问题包括用线性化欧拉方法求解的非均匀气流影响下的声传播问题和经典振动声学问题。前者采用有限差分技术实现，后者采用有限体积技术，有效地利用了现有的通用开源库。

In the research was developed general-purpose software package for multiphysical acoustic numerical simulations and its accompanying pre- and post-processing interfaces, with effort to open resulting products on the web. The multiphysical problems being focused on were acoustic propagations under influence of nonuniform air flow which is solved with linearized Euler approach, and classical vibro-acoustics. The former solver was implemented by finite-difference technique whereas finite-volume technique was applied for the latter, with the effective help of existing general-purpose open-source libraries.
