[MITgcm-support] KPP parameters not read?

[Jean-Michel Campin]

Hi Donald,

Could you attach the parameter file "data.kpp" that you are using
with specified value for difm0, difs0 and dift0 that are ignored ?

Cheers,
Jean-Michel

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.
