    Test of the European Transport Solver in the frame of Integrated Tokamak Modelling
    (Institute of Nuclear Physics Polish Academy of Sciences, 2011) Twaróg, Dariusz; Stankiewicz, Roman; Drozdowicz, Krzysztof
    The European Transport Solver (ETS) is developed in the frame of Project 3 of EFDA Integrated Tokamak Modeling Task Force. Several numerical methods are implemented in the ETS. This paper presents a method of verification of implemented numerical schemes for the case of solutions which take into account existence of the transport barrier in the tokamak plasma. A manufactured solution method for generation of exact solutions is developed for this case. The exact solutions are compared with the numerical ones for a simple transport model. Numerical tests demonstrate that numerical procedures: solvers 3 and 7 can reproduce analytic solutions with a discontinouity quite well.
