Abstract
Domestic CAE software research and development has long focused on the development of numerical solvers. Most expand mesh generation functions by integrating with foreign commercial and open-source software, which greatly limits their engineering and commercial prospects. It is urgent to develop self-controllable mesh generation algorithm library software to fill the critical gap in mesh generation and realize full-chain autonomy and controllability. This report is divided into two parts. The first introduces TiGER, a self-developed mesh generation algorithm library software by Zhejiang University, and its research progress, mainly involving the basic architecture, core functions, as well as theoretical and technical foundations of the algorithm library software. The second presents several application cases of TiGER software in typical electronic device simulation scenarios, so as to provide examples for the application of TiGER software in similar scenarios.
