Multicode turbulence simulations of diverted TCV plasmas and detailed validation against the experiment

This contribution presents preliminary results of the validation of state-of-the-art turbulence codes against well-diagnosed experiments in the TCV tokamak. The simulations were carried out by GBS, GRILLIX, and TOKAM3X codes for a Lower Single-Null (LSN) L-mode attached TCV plasma and, for the first time, in realistic size. The scenario depicted in the simulations was developed in the TCV tokamak and was optimized for this validation exercise. In the following, the level-of-agreement and comparisons of selected profiles are discussed.
