EM model was used to estimate the electromagnetic field distribution
in the whole microwave heating system and obtain their
internal heat generation. The internal heat generations were then
used in HT model for heat transfer analysis and temperature prediction.
Thus in step 3, the united simulations by coupling ‘EM
model’ and ‘HT model’ as mentioned above were carried out continuously
by PHOTO-Series (Liu et al., 2013). The estimated results
were finally opened by Femap which could show the changes in
figures or animations directly. These steps have also been introduced
in detail in Fig. 1 in Liu et al. (2013).
