“…"Using the template-based transformations, the user can robustly and efficiently define the geometric transformations according to his/her FEA objectives. Thus, new components shapes adapted to CAE software requirements are produced while the consistency of the assembly model is preserved" [3]. For example, the use of bolted junctions in assembly context is presented.…”

“…The approach of Lee [12] focuses on an integrated CAD/CAE-model, which is also part of the presented approach in this paper. The paper Templatebased geometric transformations of a functionally enriched DMU into FE Assembly Models [3] shows the use of simulation-oriented template files by a CAD-system and an external CAE-system. The usage of template files is an efficient way of defining boundary conditions and is extended in the presented approach.…”

Computations and simulations during the design process are performed with a variety of ComputerAided Design (CAD) systems. For the integration of analytical calculation methods, KBE (KnowledgeBased Engineering) approaches have been integrated quite successfully. This is particularly true for parameter-oriented inference mechanisms. Numerical methods require further developed methods especially in the consolidation between design and simulation models. This paper presents a methodological approach that automates the model transformation from the design to simulation environment. This approach bases upon so-called "smart" component models, which are processed rule-based and are enriched with component-specific knowledge for the integration of design, computation and simulation. By using simulation-oriented features and components, the preprocessing becomes more efficient.

“…This additional information provides the user with efficient means to select/process groups of components that would be otherwise tedious and error prone to identify [25]. Other interactive approaches, like Oh et al [26] propose group selection with a dynamically computed hierarchy based on the notion of gravitational proximity.…”

My Corporis Fabrica: an ontology-based tool for reasoning and querying on complex anatomical models

BackgroundMultiple models of anatomy have been developed independently and for different purposes. In particular, 3D graphical models are specially useful for visualizing the different organs composing the human body, while ontologies such as FMA (Foundational Model of Anatomy) are symbolic models that provide a unified formal description of anatomy. Despite its comprehensive content concerning the anatomical structures, the lack of formal descriptions of anatomical functions in FMA limits its usage in many applications. In addition, the absence of connection between 3D models and anatomical ontologies makes it difficult and time-consuming to set up and access to the anatomical content of complex 3D objects.ResultsFirst, we provide a new ontology of anatomy called My Corporis Fabrica (MyCF), which conforms to FMA but extends it by making explicit how anatomical structures are composed, how they contribute to functions, and also how they can be related to 3D complex objects. Second, we have equipped MyCF with automatic reasoning capabilities that enable model checking and complex queries answering. We illustrate the added-value of such a declarative approach for interactive simulation and visualization as well as for teaching applications.ConclusionsThe novel vision of ontologies that we have developed in this paper enables a declarative assembly of different models to obtain composed models guaranteed to be anatomically valid while capturing the complexity of human anatomy. The main interest of this approach is its declarativity that makes possible for domain experts to enrich the knowledge base at any moment through simple editors without having to change the algorithmic machinery. This provides MyCF software environment a flexibility to process and add semantics on purpose for various applications that incorporate not only symbolic information but also 3D geometric models representing anatomical entities as well as other symbolic information like the anatomical functions.

“…This information is utilized to enrich the DMU to help automate downstream analysis transformations. Boussuge [4] used the geometric and functional interfaces derived by Shahwan [16] to generate user-defined templates for processing repetitive arrangements, such as fastener assemblies, for FE assembly modelling. Boussuge implemented template-based shape transformations on a 250 component assembly and reduced the analysis model preparation time from 25 days to 1.5 hours.…”
