Software

1) Fluent

FLUENT is a general CFD software package used to simulate complex flows in the range of incompressibility to high compressibility. Due to the use of various solving methods and multi grid accelerated convergence techniques, FLUENT can achieve the best convergence speed and solution accuracy. Flexible unstructured grids, solution based adaptive grid technology, and mature physical models enable FLUENT to be widely used in conversion and turbulence, heat transfer and phase change, chemical reaction and combustion, multiphase flow, rotating machinery, dynamic/deformable grids, noise, material processing, fuel cells, and other fields

2) ACTRAN

ACTRAN is the most comprehensive acoustic simulation software on the market today. Based on the universal techniques of finite element and infinite element methods, ACTRAN provides a rich library of elements, materials, boundary conditions, solution configurations, and solvers. ACTRAN has now covered various aspects of vibration acoustics and flow acoustics, possessing a wide range of features combined with today's most advanced technologies, and is often used to solve challenging vibration and flow acoustics problems.

3) OpenFOAM

OpenFOAM is an open-source CFD software, an object-oriented CFD class library written entirely in C++. It uses a method similar to our daily habits to describe finite volume discretization of partial differential equations in the software, supports polyhedral meshes, can handle complex geometric shapes, and supports large-scale parallel computing. Its built-in snappyHexMesh can quickly and efficiently partition hexahedral and polyhedral meshes, with high mesh quality.
