Abstract

We discuss a new method for coupling molecular dynamics and continuum mechanics, which is based on a function space oriented approach. For this purpose, the micro scale displacements originating from molecular dynamics in the Euclidean space are extended into a Sobolev space using a partition of unity. Then, a scale decomposition is realized in L² by means of an orthogonal projection, giving rise to our new weak scale transfer operator in function space. Here, we consider the assembling process of the algebraic representation of this weak coupling operator and show that the assembling can be done in (quasi-)optimal complexity.
