[MITgcm-support] KPP parameters not read?

[Donald Slater]

Hi Jean-Michel,

Here it is.
As I said before, the simulation runs fine even if I change to e.g. “difmo = Donald.,”

Thanks,
Donald

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.
