Challenges in Mechanical Component and Process Modeling
Nowadays, the requirements of simulation of components and processes are becoming more and more demanding within the paradigm of industry 4.0. This new scenario poses a series of technological challenges that must adequately satisfy all those aspects that the industry demands not only in the technical areas but also in those that define the logistic and financial structures of the companies. For all these reasons, the goal is to explicitly expose these challenges with the aim of stimulating a debate between the different agents involved in the aforementioned simulation processes in order to provide them with robust and efficient solutions that also imply clear benefits for the industrial activity in economic and quality terms.
Challenges in Plug-and-Play CAD-CAE Integration
Physics drives design, and extraordinary effort has gone into building software simulation tools. However, users need to be able to integrate automatically with CAD systems, compose different CAE tools, and reconfigure systems on-the-fly. Intact Solutions will present outstanding challenges to achieving seamless interoperability between geometry and physics.
Geometry Processing for Collections
This talk will present geometry processing problems relevant to modeling with collections of objects, using collections of geometry representations, to account for collections of physical phenomena, and to fabricate them with collections of manufacturing processes.
A CAD tool expresses a design in a particular representation and
specific primitives. Subsequent analysis can reveal that the design
is unmanufacturable, fails to meet some performance requirement, has
poor longevity in use, etc. Determining these undesired consequences
is a forward problem. The inverse problem is how to change the design
such those undesired consequences are avoided. This can be seen as a
diagnosis problem - identifying causes for the undesired consequences.
Success on this task depends critically on the representation of
design, manufacturing, and context of use of a design. We see no
systematic approach in current CAD tools to support this type of reasoning.
Parametric Modelling Applied to Complex Geometry of Bridges
The aim of this session is to describe briefly how SENER faces complex bridge modelling within BIM methodology, by means of programmed routines that lead to parametric controlled design. Since software programs traditionally used for simple bridge modelling (e.g. Revit) lacked in specific tools regarding complex geometry, SENER was encouraged to develop a specific procedure. On this purpose, different routines have been programmed using OOP (Object Oriented Programming), such as Dynamo, so engineers can control bridge’s design by simply modifying its database. Thanks to these tailored developments, bridges’ modelling accuracy has been enhanced; and, what is more, it has entailed savings in terms of time and assets, as a result of automation and parametric based design.
Improving Morphing Techniques in Finite Element Analysis Optimization
Morphing or nodes positioning shape vectors generation in a finite element mesh is one of the most powerful ways of optimizing a component in the environment of structural analysis. These shape vectors can be treated as variables in an optimization problem leading to optimum real geometry shapes in the component. This technique has normally a very low failure rate for complex geometries in comparison with CAD parametric models generation but sometimes element shape (normally second order elements) is distorted to unacceptable values (zero Jacobian). A challenge in this field is to generate quick and robust (no distortion problems) shape vectors to allow deeper geometrical changes in a finite element model to perform better structural optimizations of components.
