Abstract
**Abstract**
The European Transport Simulator (ETS) was used to simulate a massive material injection (MMI) induced disruption based on experimental data from the ASDEX Upgrade tokamak. Experimental shot #33108 has been imported into the IMAS database and it was used in the ETS workflow. In this shot an Argon puff was used in the ramp up phase to induce a disruption. The injection was preceded by an intense ECRH heating to generate a peaked electron temperature profile, ideal for runaway electron generation. ETS was used with the imported data in an interpretative mode during the ECRH heating phase, to complete the imported dataset, filling any necessary input for the predictive phase. A predictive simulation was performed starting from the moment of MMI. The resulting runaway electron population was calculated using the Runaway Fluid model. The plasma current evolution was compared against the experimental results and benchmarked against ASTRA-STRAHL simulations of the same shot.
