Description
Recent progress in the development of a virtual tokamak platform is presented, which aims to integrate physics simulations with engineering analyses for fusion R&D. The platform, named WILL (Versatile Virtual platform for Integrated fusion simuLation and anaLysis), provides such integration by flexibly and seamlessly bridging data from tokamak operations, experiments, and simulations. WILL builds upon the enabling technologies and software originally developed for the Virtual KSTAR project, but restructures and modularizes them by separating KSTAR-specific features and generalizing the framework for application to arbitrary tokamak devices.
The key technologies and software incorporated into WILL include: (1) unstructured meshes for discretizing arbitrarily complex 3D models and storing physics and engineering data, (2) a dedicated data framework for managing diverse fusion data, built upon IMAS and HDF5 technologies, (3) Python and C++ libraries for 3D data analysis, such as collision detection between dynamic and static objects, and (4) 3D visualization software based on the Unreal and Unity3D graphics engines.
With these enabling technologies, WILL supports full 3D fusion simulations and analyses with model fidelity suitable for engineering R&D. Several examples of such 3D simulations and analyses are reported, and ongoing efforts are also introduced that aim to establish WILL as a platform for virtual experimentation.
