今天是MMM2012 SINGAPORE的第一天,原来在BROWN University 的 William Curtin 教授作了第一个报告,这是我听到的最好好的报告之一。他的主题是:Perspective on multiscale materials modelling: Why, What, How, Who, Where and so what? 我主要理解2点

(1)What is multiscale material modelling?

Wiki: In engineering, mathematics, physics, meteorology and computer science, multiscale modeling is the field of solving physical problems which have important features at multiple scales, particularly multiple spatial and(or) temporal scales. Important problems include scale linking (Baeurle 2009[1], de Pablo 2011[2], Knizhnik 2002[3], Adamson 2007[4]). 

(2)This internal conference on multiscale material modelling was First held in 2002, after 10 years, what we get? 

We have key understanding: there are two key points: Different scales information passing and concurrent coupling.for scale information passing, for Lower scale: what is the key information needed to pass up;for higher scale:  Theory can accept the appropriate lower-scale information.
