"Three-dimensional Dynamic simulation and visualization Method of Sea Waves" has been awarded the invention patent certificate (patent number: ZL202211436973.0).

The invention discloses a three-dimensional simulation method for sea surface wave motion. Based on the analysis and simulation of the change of the shape and position of the sea surface, the process of wave movement can be divided into two sub-processes: elevation change and horizontal movement. For elevation changes, three-dimensional grids are obtained based on fixed horizontal grids and sea level elevation function mapping, and the direction calculation method of top point method is given to realize smooth surface display of sea waves. For horizontal movement, a color change method based on mapping and moving speed of water quality points is proposed to realize the display of water flow in the horizontal direction. Based on the proposed simulation method, the invention also realizes a three-dimensional wave dynamic simulation device, which consists of five modules, namely horizontal grid generation, three-dimensional vertex management, point method direction calculation, map coordinate updating and result display, which can support the three-dimensional dynamic visualization of sea waves in various forms.

Compared with the existing technology, the invention can be applied to the three-dimensional dynamic simulation and visualization of various types of waves including measured waves, regular waves and random waves, and can support the division of horizontal grids in different ranges, different precision and complex situations. It has good scalability, and provides an efficient, reliable method and convenient tool for the simulation of sea waves. It provides a foundation for the application of information digitization and visualization in Marine industries such as Marine ecological environment, Marine engineering, Marine transportation and so on.

Note: The inventors of the patent also include doctoral students Liu Yi, Academician Zhang Jianmin and Associate Professor Li Binbin.

On February 9, the Winter vacation social practice detachment of Tsinghua University visited the Institute for Ocean Engineering  to carry out exchange activities. The detachment consists of 55 undergraduates majoring in civil water conservancy and ocean engineering, energy and power engineering, aerospace engineering, theory and applied mechanics, etc.

The detachment was divided into three groups and visited the engineering pool laboratory, the digital twin laboratory (our research group) and the gas hydrate laboratory located in the Ocean Building. Teachers and members of the Institute for Ocean Engineering  explained the visiting group. Afterwards, the teachers and students of the Institute had a discussion and exchange with the members of the detachment. I presided over the exchange meeting and introduced the history and development orientation of Shenzhen International Graduate School and Institute for Ocean Engineering. The detachment held in-depth discussions with the teachers of the Institute on such topics as cooperation and development, national needs and future trends of ocean engineering, college talent training and social responsibility, hoping to further establish a more long-term and more common communication mechanism to promote the exchange and academic cooperation between teachers and students in Beijing and Shenzhen.

The successful holding of the winter vacation social practice exchange, let students further contact with society, understand society. I hope students can exercise themselves in practice, close to the society with practical actions, dedication to society!

The latest software achievement of our research group, "Intelligent Monitoring System for Floating Fan Structure Health", has obtained the copyright registration certificate of computer software (registration number: 2023SR0167488).

The system is mainly oriented to the structural health monitoring of the offshore floating wind turbine, and provides a platform for checking the structural status of the floating wind turbine and simulating the structure of the floating wind turbine. Users can browse the various parts of the floating fan through three-dimensional interaction, and can also simulate and analyze the structure related to the floating fan on the interactive interface, so as to realize the overall control of the structural performance of the fan.

The system is composed of data management module, structural force analysis module, three-dimensional graphic display module, user interaction interface and other main modules. The data management module extracts and manages the required model and monitoring data from 3D model files or sensor monitoring data files; The structural stress analysis module is used to calculate the deformation and stress distribution of the structure under given load conditions. 3D graphics display module realizes real-time visualization of 3D model and structure state. User interaction interface module is used to deal with mouse, keyboard and other user input, and realize the interactive display of 3D model.

The main developers of the system include doctoral students Liu Yi and Min Yantao and master's student Ning Houchun, with guidance from Zheng Xiangyuan, a researcher at the Institute for Ocean Engineering, Tsinghua Shenzhen International Graduate School. The research was supported by the Guangdong, Hong Kong and Macao Team Project of the Guangdong Regional Joint Foundation, the Key Project of Stability Self-help for Shenzhen Institutions of Higher Learning and the China Institute for Ocean Engineering (Qingdao).

In order to promote the standardized management and flourishing development of academic conferences in the field of science and technology, and to serve the self-reliance and self-improvement of high-level science and technology, the China Association for Science and Technology has issued the Guidelines for Important Academic Conferences (hereinafter referred to as the Guidelines) for five consecutive years since 2018, and has mobilized 171 national societies/association of societies and the Chinese Academy of Engineering to participate in the recommendation, and recommended 721 high-quality academic conferences annually. Among them, 82 national societies participated in the recommendation of the Guide for five consecutive years, and 34 brand academic conferences were selected in the Guide for five consecutive years.

Among them, the "National BIM Academic Conference", led by Professor Jianping Zhang of Tsinghua University and initiated by myself, hosted by the Building Information Modeling (BIM) Committee of the China Graphics Society, has been included in the "Guide" for five consecutive years! I also organized and chaired the keynote reports of the 1-6 sessions as Secretary-General of the General Assembly.

Welcome to continue to pay attention to the national BIM academic Conference!
