By a News Reporter-Staff News Editor at Physics Week -- Data detailed on Computational Physics have been presented. According to news reporting originating from Buffalo, New York, by VerticalNews correspondents, research stated, "In computational mechanics, molecular dynamics (MD) and finite element (FE) analysis are well developed and most popular on nanoscale and macroscale analysis, respectively. MD can very well simulate the atomistic behavior, but cannot simulate macroscale length and time due to computational limits."
Our news editors obtained a quote from the research from the State University of New York, "FE can very well simulate continuum mechanics (CM) problems, but has the limitation of the lack of atomistic level degrees of freedom. Multiscale modeling is an expedient methodology with a potential to connect different levels of modeling such as quantum mechanics, molecular dynamics, and continuum mechanics. This study proposes a new multiscale modeling technique to couple MD with FE. The proposed method relies on weighted average momentum principle. A wave propagation example has been used to illustrate the challenges in coupling MD with FE and to verify the proposed technique."
According to the news editors, the research concluded: "Furthermore, 2-Dimensional problem has also been used to demonstrate how this method would translate into real world applications."
