Simulation-driven design has become an effective methodology for improving the design process in terms of both time and cost. The high-fidelity and efficient visualisation of multidisciplinary simulation results of complex products is crucial for helping designers improve their design. One of the key challenges is to display and view multidisciplinary simulation results that are heterogeneous and tool-specific. In this study, a uniform intermediate model which supports high-fidelity and efficient visualisation of multidisciplinary heterogeneous simulation data is proposed and developed. Firstly, the problem of generating a uniform intermediate mesh model is formalised and represented as an optimisation problem. Then, the genetic algorithm is employed and improved to optimise the uniform intermediate mesh model globally and locally after the direct initial (D-initial) mesh model is refined based on the hybrid mesh size field. Finally, the mapping and interpolation relationships between the uniform intermediate mesh model and the simulation mesh models of different disciplines are established to implement simulation results visualisation in a CAD platform. To improve computational efficiency, two strategies are deliberately employed, namely indexing and parallel computing. Several experiments are conducted to demonstrate the performance of the proposed approach.

“…In 2007-2010, Léon et al [5][6][7] proposed a new software environment for CAD/CAE integration called a mixedshape representation, which integrated design methods, models, and tools dedicated to finite element model preparation. This representation has three components: a Brep NURBS topology, a facetted model, and a high level topology (HLT).…”

Many complex mechanical products can be considered as multibody systems; 3D computer-aided design (CAD), multibody dynamics, finite element-based strength and fatigue analyses, optimization, and other CAE tools, are often used to develop this kind of product. But design is difficult and challenging because of information inconsistence among different engineering domains, and isolated information model islands exist. Lots of research are attracted to design and analysis information integration, but attentions are mainly focused on integration of CADfinite element analysis (FEA), supporting the bottom-up design principle, while multibody dynamics analysis for analyzing global performance of a mechanical system is rarely considered, which follows the top-down design principle. In this paper, a novel multilevel system representation modeling framework for supporting both bottom-up and top-down or mixed design methods is proposed. It can integrate the product design CAD models with multibody dynamics, finite element-based strength and fatigue analyses, realizing a CAD-dynamic-FEA-fatigue analysis integration. It can also support data exchange and transfer in multidomain analyses. The framework is illustrated with a case study of a load haul dump (LHD) design using currently available software tools. Furthermore, a design case study of the working unit of the LHD is given to highlight the applicability of the modeling framework for multibody mechanical systems. It has been demonstrated that the framework can describe information exchanging and integration among CAD, FEA-based strength and fatigue analyses, and multibody dynamics analysis during a multibody mechanical product design process.

“…For example, in [20] and [21], the authors propose the interfacing of product views through a mixed shape representation that integrates different data representations, basically CAD geometry and facetted geometry, in order to bring the design and the analysis model closer together. Representation in a structured way, and can have semantics associated with them.…”

The paper proposes a new approach for managing two products lifecycles in the context of collaboration between aircraft OEM and their equipment suppliers. The concept of entities and specific roles are used to improve the semantic interoperability between both aircraft and equipment projects' data. These concepts are also used to formalize the relation between various processes that guarantee the connection between the aircraft and the assembly equipment lifecycles. The aim of this integration approach is to enable the information sharing between OEM and suppliers. It intends to enlarge the role of suppliers in the development process of fixture equipment, which are used in the aircraft assembly process.
