Trinity3D: a time dependent turbulent profile predictor for stellarators and tokamaks

The T3D code predicts the macro-scale profile evolution using first principles gyrokinetic and neoclassical estimates of particle and heat flux. In particular, the GPU-native delta-f flux tube gyrokinetics code GX is used for turbulent transport, and KNOSOS or SFINCS or the analytic Chang-Hinton model is used for neoclassical transport. Source terms for heating and fueling can be provided by data files or analytic expressions; recent updates allow interface to higher fidelity source terms, such as the TRAVIS code for electron cyclotron resonance heating. Several simulations will be presented to demonstrate the capabilities of the framework for transport modeling in stellarator and tokamak magnetic confinement fusion.
