Abstract


Due to increasing product- and process-requirements and shorter development periods the usage of numerical simulations has become an essential part of the product development process. This has led to expose simulation to not only the CAE experts but also to less experienced users such as designers. However, such users typically do not have the expertise to perform simulations from the ground up and need appropriate help systems.



 



Therefore, the aim of the Bavarian Research Cooperation FORPRO² for “Efficient Product and Process Development by Knowledge based Simulation” is to increase the efficiency of virtual product and process development. This is achieved by creating a simulation environment that allows corresponding users to automatically benefit from expert practices and knowledge. As a result, non-expert users can produce reliable results for virtually optimizing design parameters. This will allow shifting work load from the simulation engineer to the designer. As a consequence, the simulation process will become more agile and quick without compromising on quality of the simulation and the final product.



 



The goal of the simulation environment is to provide the necessary situational simulation knowledge as a function of decisive factors such as the phase in the development process, the manufacturing processes employed, and the company's individual circumstances. Considering such a wide range of factors, results in several challenges in the development of the simulation framework. Some of the challenges are associated with (manual or automatic) extraction processes of simulation knowledge from existing sources and the publication of the knowledge to the end user in an adequate manner.



 



The presentation will demonstrate the implementation of the central knowledge environment within the framework of a commercial SPDM system. Special emphasize will be laid on presenting an automatic acquisition of simulation knowledge from validated simulation reports by means of KDD-processes (Knowledge Discovery in Databases). The overall approach is demonstrated by considering the use case of performing a numerical FE simulation with real life geometry (including deviations caused by the manufacturing process) instead of ideal geometry from the CAD system (see image below for a the conceptual workflow for this use case).
