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

在这项研究中，开发了多物理声学数值模拟的通用软件包及其附带的前后处理界面，并努力在网上开放结果产品。重点研究了非均匀气流作用下的声传播问题，用线性化欧拉法求解，以及经典的振声学。前者用有限差分技术实现，后者用有限体积技术实现，有效地借助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.
