Towards Interoperable X3D Models and Web-based Environments for Engineering Optimization Problems

Within a multidisciplinary engineering workflow, we find interactions between different design teams, where each team has its own design objective and continuous need to present and share results with other groups. Common engineering environments are equipped with advanced modeling and simulation tools, especially introduced to improve engineer’ s productivity. The problem is that the varieties of data models are used by disparate software at various design stages, resulting in duplicated, quite large 3D models. To address such engineering problem a FSI (Fluid Structure Interaction) test case was selected. It involves numerical simulations of a multi-component box structure used for the drop test in a still water. The numerical simulation of the drop test is performed through combined used of the FEM (Finite Element Method) and CFD (Computational Fluid Dynamics) solvers. The important aspect is the design of a common graphics X3D (eXtensible 3D) model, which combines the FEM data model, which is coupled with the CFD data model in order to preserve all the relationships between CFD and FEM data. The proposed solution is based on associating the semantic information to the 3D models. It involves two web based software standards: X3D and Semantic Web. The focus is to enhance the visualization and manipulation of the graphical content in a distributed engineering network. The presented software architecture is designed to support ontologies: to interface knowledge-based systems, to promote a web-based software solution and to enable automation of perpetual engineering tasks. The challenge is to apply the "latest" available software technologies, such X3D and OWL (Web Ontology Language), and to demonstrate the modeling of heterogeneous data sources, their interoperability and 3D visual representations to enhance the end-users interactions with the engineering content.
