报告简介：

In this talk, we present an encompassing simulation workflow based on the RAPTOR transport solver, evolving the plasma profiles dynamics by solving the coupled dynamics of current density diffusion, heat and particle diffusion, and the MEQ free boundary equilibrium suite. This coupled workflow is routinely used at TCV for shot-preparation, real-time control and post-shot interpretation. RAPTOR has been coupled to the inverse equilibrium solver FBT, the forward equilibrium solver FGE and the equilibrium reconstruction code LIUQE, respectively to design more accurate feedforward poloidal field coil traces, to validate magnetic controllers in flight simulator mode and to obtain improved real-time kinetic equilibrium reconstructions. Finally, recent extensions of the RAPTOR physics base will be highlighted, including  modelling of tungsten accumulation in ASDEX Upgrade and modelling of tearing mode dynamics with the comprehensive Modified Rutherford Equation (co-MRE).
