The European Transport Solver: An Integrated Approach for Transport Simulations in the Plasma Core
The "European Transport Solver" (ETS) is the new modular simulator developed within the EFDA Integrated Tokamak Modelling (ITM) Task Force*. Ultimately, it will allow for the entire discharge simulation from the start up until the current termination phase, including controllers and sub-systems. The paper presents the current status of the project towards this ultimate goal. It discusses the design of the workflow, verification and validation of integrated modules. It presents the first results obtained on impurity simulations and on neoclassical tearing modes, as well as the "proof of principle" tests performed on transport ­ free boundary equilibrium coupling and on transport ­ turbulence coupled simulations.
