“…Most researchers utilized DINA to simulate the plasma in VDEs in order to calculating electromagnetic loads of the vacuum vessel and the in-vessel components. By using the same method but a new method to simplify modeling process, Sunil Pak et al have done much effective electromagnetic load calculation work on the ITER machine [9]. In their study on slow downward VDEs, it is indicated that the vertical forces exerted on the 20 sector of the divertor model get up to 5 MN from 0 MN in a linear way during about 400 ms, and decay to 0 MN in a negative exponent way during the following 700 ms.…”
