[MITgcm-support] Floats Advection

[Sergio Jaramillo]

Hi,

I am setting MITgcm to model the flow in a rotating table. First I tried 
an example with  cartesian coordinates and it worked very well, I put 
some floats and they are advected in the way I expected. But now I am 
running the model with curvilinear coordinates, and even though I have 
good results regarding the flow, my floats don't move  at all this time. 
The positions of the floats that I used are in XC, YC coordinates and I 
don't know if this is correct. I checked in flt_functions.F and the 
global2local_i, and global2local_j that come out are totally unrealistic.

I hope that some one can help me with this problem.


Thanks,
