• Non-local model can be tuned
to give the temporal evolution
in W th qualitatively in line with
experiment;
• Density trend is not so well
reproduced (adjustment of
recycling could help);
• Discrete ELM model
undergoes a series of
repetitive L-H-L transitions
caused by sudden energy flux
drop after L-H transition,
which are not usually
observed in experiment
