Offer Description
The position is to be filled on a fixed-term basis for a period of 36 months. The successful applicant will be given the opportunity to pursue a doctorate.
This contract is funded by the European Union’s Horizon Europe research and innovation programme under the MSCA DN project GECKO (GA No 101073106)
The main objective of the GECKO project is to bridge the existing gap between the CAD and the computational models (CAE) and integrate them within the industrial workflow. This will imply collaborating with industries in enhancing the adoption of the technology within commercial solvers and adapting existing open source frameworks so that they can hook into the industrial practice and thus remain relevant in the future.
In the practice, this implies ensuring that open-source solvers, developed in the academia for both solid and fluid dynamics, are able to use as an input domain any CAD geometry, even in cases in which the geometrical definition is not optimal, i.e. poorly defined or “dirty” geometries with no additional operations nor user intervention.
Motivation and Objectives of the Planned Research
Development and systematic assessment of high-accuracy and robust structural mechanics elements for large deformation Isogeometric B-Rep Analysis (IBRA). It is a well-known fact, that IGA provides a perfect basis for high quality simulations due to possible remarkable convergence behavior and moreover, very accurate geometry descriptions. The latter advantage is even more pronounced in cases with large deformations, because the excellent geometry modeling in combination with the higher order shape functions results also in very accurate and smooth surfaces in the deformed configuration. Special challenge in this regard is the realization of the patch coupling conditions at patch boundaries - or even more severe, along trimming curves- in order to keep the high geometrical accuracy also at those specific locations in the case of large deformation processes. To enable such simulations, the availability of capable and robust IBRA-element formulations is crucial and also the processing of the CAD-models in order to have all required data for the IBRA-model directly from the CAD, i.e. to have a fully CAD-integrated approach, which is of extremely high relevance also for industry. The required implementations are planned to be inside the open-source Kratos-Multiphysics code.
Expected results:
- Investigation and further development/refinement of high-accuracy and robust beam and shell elements. Special focus on efficiency and suitability to establish various different patch coupling approaches and to apply different types of boundary conditions (e.g. also to facilitate the use in contact mechanics or other coupled problems).
- Assessment of different patch coupling formulations (penalty, Lagrange, Nitsche, …) with respect to ease of implementation, accuracy, numerical robustness. Special emphasis is on their performance in large deformation IBRA.
- Investigation and development of interfaces for CAD-integrated IBRA. Special focus is on the preparation and supply of necessary data for patch coupling and trimming operations and their treatment in structural mechanics.
