SUMMARY:The Fusion Digital Twin: Integrating Databases, Simulation, AI Sur
 rogates and Visualization for Design Workflows of Fusion Devices
DESCRIPTION:Florian Cabot (EPFL)\n\nDesigning elements for nuclear fusion 
 devices is a challenge at the crossroads of engineering and HPC, requiring
  data from simulation codes, experimental databases, and engineering tools
 . Previous work shows that separate applications of heterogeneous software
  greatly complexify the engineering analyses of fusion systems. Therefore,
  flexible and scalable workflows integrating scientific tools can streamli
 ne the design process, aiming to reduce development effort and cost.\n\nTh
 is work presents the EPFL-NVIDIA Fusion Digital Twin (FDT) project, which 
 integrates multiple software applications within a single platform, enabli
 ng user-defined workflows for coupled physics–engineering simulations. At 
 the core of the FDT service-based architecture lies the NVIDIA Data Federa
 tion Mesh, used for orchestration and data exchange between services. Simi
 larly, the user interface is built upon the NVIDIA Kit App and RTX technol
 ogies, enabling photorealistic visualization of integrated data. We demons
 trate the integration of multiple services within FDT, including adapters 
 for the DEFUSE databases, Ansys, Matlab, SLURM, as well as a SOLPS-ITER fa
 st surrogate model called SOLFS. These services interface with each other 
 to produce a comprehensive plasma heat flux–component thermal response vis
 ualization of multiple TCV divertor configurations.\n\nPlans for extending
  FDT to 3D device wall models, as well as additional physics capabilities,
  will also be discussed.\n\nDomain: Engineering, Physics, Computational Me
 thods and Applied Mathematics\n\nSession Chairs: Gilles Fourestey (EPFL) a
