Cover Story: The aerospace industry is one of the leading figures in the development and improvement of techniques for the design of new products. One of the most promising developments of recent decades is the exploitation of digital models that make it possible to evaluate design solutions and simulate the behavior of individual systems as well as their interactions. The goal is to be able to predict and analyze all aspects of an aircraft much in advance of its industrialization in order to heavily reduce the time as well as costs of product development and to guarantee the flexibility to test a multitude of solutions. The main issue in this context is the complexity of creating models that are capable of accurately sizing and simulating multiple interacting systems, thus considering the constraints imposed by the need for their mutual compatibility.
