Modeling of complex mechanical systems faces challenges throughout the systems lifecycle. From keeping track of evolving system requirements during development to design configuration and version control for legacy models. Methodologies such as Model-Based System Engineering (MBSE) emphasize the utilization of information already embedded in models to aid in the propagation of information between disciplines and stakeholders. By automating the creation of digital artifacts and standardizing their formatting, robust connections between specialized engineering tools can be generated and full adoption of MBSE is possible. One such connection that must be established for MBSE adoption is between tools for geometrical design, such as CATIA V5, and tools for system simulation. The Functional Mock-up Interface (FMI) and System Structure and Parameterization (SSP) standards have been shown to provide a viable standardized format for coupling geometrical Computer Aided Design (CAD) models with system simulation models. However, the application of such standards coupled with geometrical design is still in its infancy and more research is needed to prove its usability and establish functional methodologies in an industry setting. The goal of the thesis was to further develop the application of the SSP standard on a geometrical CAD model of a Coolant Distribution System (CDS), and through automation estimate deterministic simulation parameters. The work was carried out at Saab Aeronautics in Linköping, Sweden. By utilizing the industry as laboratory method, the industry-grade geometrical CAD models were used to converge the research and the industry needs to make the resulting proposed methodology applicable in an industry setting. The work showed that with the help of automated frameworks, deterministic simulation data can be retrieved from new and legacy geometrical CAD models of CDS whilst complying with version control protocols. The implemented automation frameworks were able to estimate pressure loss coefficients for the different parts included in the CDS such as pipes, hoses, and couplings. Additionally, other needed simulation data such as lengths, insulation coverage, and inlet coordinates for the simulation components was also extracted from the geometrical model. By utilizing the presented method of isolated mapping, parts in the geometrical CAD model could be mapped to the correct simulation component whilst offering substantial flexibility and minimal editing of the models. Ultimately, the work showed that the tools needed for using automation for interoperability between geometrical design and system simulation does already exist. With automation frameworks and necessary knowledge integrated into the geometrical models, the field of geometrical design is shown to be ready for MBSE adoption.
