• Recent example of selfconsistent predictive modelling of impurity redistribution on top of main ion density and ion and electron temperature simulation; • Note significant temporary rise in line radiation following each type-I ELM (as observed in experiments) V.

Global model describes better H-L transition but fails to reproduce L- H transition due to persistence of strong dithering; On the other hand, local model reproduces the dynamics of L-H transition reasonably well but fails to reproduce fast H-L transition; Much more work is needed to bring density evolution in better agreement with experiment; Impurity radiation might play an important role in the dynamics of H-L transition; Systematic comparison with experimental results are needed before applying either model to ITER.
