Computer Numerical Simulation

Numerical simulation is such a simulation process, through the calculation run on the large capacity and high performance computers, to reproduce the values at all the temporal and spatial grid nodes of the discretized domain/component or master equations, initial and boundary conditions of interest, etc. It can also give the graphical displays and results analysis, showing how the data change corresponding to the external affections on the domain/components. 


The deployment of computer simulation technique in engineering emerged in the 1960s; hand-in-hand with the rapid growth of the computer and the software development, computer simulation has been widely applied in Western scientific research units and the industrial sectors in the ‘80s and ‘90s of the 20th century. Nowadays, computer simulation has almost extended to all fields of scientific research and industrial practice, and made a substantial contribution to the accumulation of scientific knowledge and the improvement of production efficiency. However, the development of such technique in our country lags some way behind comparatively, and the commercial softwares are rather rare. Thus, there is still a great space for its development.

 

CEAM Numerical Simulation Institute aims to attract more talented people to develop computer simulation technique and promote its application in novel materials research and advanced manufacturing, so that we can make substantial contributions to the development of novel materials research and processing technology in China, and digitization, informationization, intelligentization and internationalization of Chinese industries.
