Design for IGA-type discretization workflows

The GECKO project aims to bridge the gap between Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE) by integrating computational models into industrial workflows. Traditional CAE modeling is slow and error-prone in its preprocess phase, making it inefficient for industries like automotive and aerospace where the mesh generation can take up weeks or even moths to be completed and cleaned. To address this, GECKO leverages Isogeometric B-Rep Analysis (IBRA), which preserves exact CAD geometries in numerical simulations, and the Shifted Boundary Method (SBM), as alternatives for the application of boundary conditions on trimmed edges. To achieve its objectives, the GECKO project brings together five world-class research institutions: CIMNE-CERCA, TUM, UNIPV, KU Leuven, and AUTH, which have recruited 10 highly qualified and motivated Doctoral Candidates (DCs): DC1- Nicolò Antonelli (CIMNE) works on CFD techniques in IGA using a shifted boundary approach, DC2- Polytimi Zisimopoulou (CIMNE) focuses on IBRA applications in solid mechanics, and DC3- Andrea Gorgi (CIMNE) develops a shifted boundary method for implicit contact mechanics in IGA. DC4- Juan Antonio Camarotti (TUM) investigates co-simulation strategies for multi- field problems in the context of IBRA and unfitted methods, while DC5- Maram Alkhlaifat (TUM) studies large deformation structural elements with IBRA. DC6- Lucas Venta (UNIPV) develops mathematical tools for immersed IGA, and DC7- Angelos Pagonas (UNIPV) focuses on Immersed IGA for Structural Dynamics. DC8- Doğuhan Kiliçarslan (KU Leuven) works on efficient transient acoustic analysis through IGA and model order reduction, while DC9- Philip Le (KU Leuven) develops MOR techniques for coupled vibro-acoustic systems. DC10- Wei Li (AUTH) focuses on implementing IGA in the design and analysis of machine elements. Additionally, the project has five associated partners, four leading companies (BETA_CAE, IDIADA, DYNAMORE, and AIRBUS), ensuring practical relevance, knowledge transfer, and alignment with industry needs, and UNIFI, which provides key expertise in hierarchical splines for refinement and coarsening adaptively. Additional support from UPC and Leuven.Inc helps provide doctoral training and stimulate the DCs’ entrepreneurial skills, creating a strong connection between academia, industry, and innovation.

Project objective

After more than a decade of research, IsoGeometric approaches are starting to make inroads into commercial solvers, and thus starting to be relevant in the industrial practice. Outstanding challenges still exist in the use of the underlying CAD technologies, and in particular in the use of “trimming”.The main objective of the GECKO project is to help solving the outstanding difficulties by improving the current state of the art and by integrating academic research within the industrial workflow. This will be achieved by 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. In this regard, an efficient and robust solver design must be implemented to be capable of performing seamless “Design-through-analysis” workflows . The goal will inherently imply collaborating with the pre/post processing industry (represented in the proposal by the company BETA-CAE), with solver vendors (DYNAMORE) and end users (IDIADA) to ensure that a smooth path is defined to allow such convergence. The overall project outcome will be to form a new cohort of experts on the topic and to enhance the open source tools and operational workflow so that they can effectively complement commercial based approaches. This in turn will allow addressing relevant bottlenecks, as identified by the industrial partners, so that the solution can be eventually backported into commercial solutions. Another important objective in the GECKO project is to empower and generalize the currently available solutions when dealing with complex non-linear models (Solvers) in Computational Fluid Dynamics (CFD), Computational Solid Mechanics (CSM), acoustics, vibro-acoustics, Reduced Order Models (RoM) and surface mapping.
