Description of the model Application to 2D transport modelling Application to 3D turbulence modelling
Résumé
Two types of fluid models are widely used to model edge plasma:-2D transport codes such as SOLPS, UEDGE or SOLEDGE2D assuming plasma axi-symmetry and where cross-field turbulent transport is emulated by empirical diffusion. These codes account for neutrals (fluid or kinetic) and impurities and are key tools to interpret experiments. They lack predictability due to their poor description of turbulence.-3D turbulent codes such as BOUT++, GBS or TOKAM3X which are able to self-consistently model turbulent transport but often rely on idealistic plasmas. The description of realistic tokamak geometry, neutrals or impurities is not always addressed. We propose here to capitalize on the experience in developing SOLEDGE2D and TOKAM3X at CEA to create a new code SOLEDGE3X integrating the advantages of the two codes and thus being able to simulate complex multi-species plasma in realistic geometry, either in transport mode (2D) or turbulent mode (3D).
