Digital twins can be based on data, physics, rules, behaviors, and geometry models/features. Together with the conventional data-based approach that has been used for decades, other models that are generally based on engineering simulations allow the detection of problems that may occur in components, testing existing or new configurations, and creating and performing what-if analyses. Accordingly, a digital twin consists of two parts as a passive data part and an active program that performs a task. The models associated with physics, rules, behaviors, and geometries form the “program” part for the purpose of simulation. The concept of simulation-based digital twins (SbDT) is elaborated from an architectural perspective. The objectives of the study are to provide improvements and/or novel techniques in defining an architecture for SbDTs. To this end, relevant the literature survey is undertaken in the corpus based on the relevant methodology, and it is proposed to elaborate capabilities and metrics. These two can be associated with functional and non-functional requirements of a product or system respectively. The inclusion of design patterns, abstraction levels, verification, and validation concepts are also checked within the corpus, although these are not included in specific keyword searches in the literature. With such discussions in hand, a general architecture considering these aspects is proposed.
