Hi Patrick,

unfortunately I cannot plot any state variable, because they are  
already all NaN after the first timestep. I am plotting taux, because  
it is not affected *as much* in the first timestep.
Basically the ice model is blowing during the first timestep and the  
only reason, why I have a surface stress (oceTAUX, not EXFtaux)  
that's only affect along the edges is, that I do only one iteration  
in the EVP solver (if I use the LSR solver with more than one  
iteration, all is lost anyway). Maybe I should follow Chris'  
suggestion and check the whole thing in, so that you can run this too.
