"The multiscale analysis has become a common tool in the study of many complicated structures such as composites. In this regard, two possible modeling strategies, so called coupled and uncoupled approaches, are available. While the uncoupled approach treats individual scales separately and thus divides the analysis typically into two or three mutually independent steps, the coupled approach allows combining analyses at all scales in a common framework. Clearly, formulation of a macroelement belongs to the group of coupled approaches. It starts from meshing the micro or mesostructure into a net of finite elements with associated global stiffness matrix. All inner degrees of freedom (dofs) of the finite element mesh are then condensed out together with applying certain multipoint constraints to unwanted boundary degrees of freedom.
