Nearly 400 scientists from 15 countries came to Beijing to discuss cutting edge simulation technologies this weekend.
They were taking part in the 2008 Asia Simulation Conference and the 7th International Conference on System Simulation and Scientific Computing.
Simulation is an attempt to model a real-life or hypothetical situation on a computer so that it can be studied.
The technology helps engineers design complicated products, such as cars, planes or medical tools.
It is also widely used to simulate motion which improves athlete performance.
Tang Xiaoqing, vice president of Beijing University of Aeronautics and Astronautics said, the goal of the conference was to increase international academic exchanges in modeling and simulation. It brought outstanding researchers together to share their expertise and experience, he added.
Simulation technology and high performance computing have become increasingly popular in engineering fields. Tang believes it's why international exchange and an expert forum, like the one held this weekend, are so important.
The conference was initiated by Chinese, Japanese and the Republic of Korea simulation academic associations.
