| Research Abstract |
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.
