Introduction to Mesh Generation and Adaptation and Related Mathematical Problems

12月5日（周五）14:00-15:00，南楼229

Mesh generation is the prerequisite of numerical methods (e.g., Finite Element Analysis FEA, Computational Fluid Dynamics CFD).

There are many theoretical and practical difficulties in automatically generating good quality and adaptive meshes in 3d. This talk focuses on a methodology based on the well-known Delaunay-Voronoi structure. We will present the state-of-the-art development on automatic generation of high-quality surface and volume Delaunay meshes for arbitrarily complex and challenging industry geometries. Furthermore, we will discuss related mathematical problems and review the latest developments in the field.

报告人简介：Hang Si is a Professor at the School of Software, Dalian University of Technology (DLUT). He earned a Bachelor's degree in Electronic Engineering from Hangzhou University (now Zhejiang University) in 1994, a Master's degree in Computer Science from Zhejiang University in 2002, and a Ph.D. in Mathematics from Technische Universität Berlin (TU Berlin), Germany in 2008. From 2002 to 2020, he worked as a Senior Researcher at the Weierstrass Institute for Applied Analysis and Stochastics (WIAS) in Berlin, Germany. He worked as a Senior Software Architect at Cadence Design Systems Inc, San Jose, CA, U.S.A from 2020 to 2024.

Prof. Si's research focuses on solving practical engineering problems through rigorous mathematical theories. He spent over 20 years conducting algorithmic research on mesh generation. His major achievement is the open-source 3D tetrahedral mesh generation software TetGen (http://www.tetgen.org). This software is widely used in engineering and academic research. It has also been commercially licensed to numerous companies, generating over $1 million in licensing fees. For this work, he received the SGP Software Award in 2012. At Cadence, he led a team and developed an unstructured mesh generation engine, which made a foundational contribution to the company's electromagnetic field and thermal analysis software, earning customer trust in the market and generating significant commercial profits.

Upon returning to China, Prof. Si will dedicate himself to developing next-generation mesh generation algorithms and software.
