[MITgcm-support] KPP parameters not read?

[Dimitris Menemenlis]

Did you specify "useKPP=.TRUE." in data.pkg?

In contrast, if I insert something silly into data.icefront (e.g. icefrontthetasurface = Donald), the simulation immediately stops. This suggests to me that somehow difm0 (and perhaps the other parameters in data.kpp) are not actually being read.
