Method for using coupled FEA analyses of different levels of organization within an entity to analyze the entity

A method and computer-implemented system for coupling multiple, concurrently-running FEA analyses of an entity that has multiple levels of organization in a way that enables each analysis to inform and be informed by analyses of higher and/or lower levels of organization in the entity. The method and preferred system includes describing an entity at multiple levels of organization (for example, multiple length scales) with FEA models and defining the interplay between the various models. Further, the method and preferred system includes initializing, managing and controlling the interaction between the multiple, concurrently-running FEA analyses. The resulting overall, improved analysis provides more accurate modeling information about each individual level of organization than traditional "single-level FEA"analysis of that level by accounting for the behavior of and interaction between multiple levels of organization in the entity.
