报告内容摘要:
Multiscale modeling and simulation is a quickly evolving area of research
that will have a fundamental impact on computational science and applied mathematics.
The traditional mathematical modeling is based on single-level physical laws, with
applying the three conversation laws (mass、momentum、energy) and constitutive relation,
forming PDE (such as Navier-Stokes equation). Computational methods and mathematical
modeling are two individual processes. With the rapid development of computer,
computational method and its technique is getting huge achievement accordingly.
Multiscale modeling is driven mainly by the use of mathematical models in applied sciences,
in particular material sciences, chemistry, fluid dynamics and biology. Problems in those
area are often multi-physical laws of different character, following is in common use:
Quantum Mechanics, Molecular Dynamics, Kinetic Theory and Continuum Theory. The aim of
multiscale modeling is to model the theoretical input to a coarse-grained model from
a more detailed microscopic model, by passing the necessity of empirical modeling.
In this talk, a coupled multiscale approach will be discussed. We will also introduce
soft matter/complex fluids and the device simulation of semiconductor technology.
